Food & beverage automation in Australia. A manufacturer's guide.

The Australian food & beverage automation landscape.

In 2024, Australian food and beverage manufacturing turnover reached $173 billion, with nearly 300,000 people employed across the sector. More than a third of those jobs sit in regional communities (AFGC, State of the Industry 2024). Automation maturity across this base varies wildly. Multi-line dairy plants run ISA-88 batch sequences with full MES traceability at one end; bakery operators still schedule production from a whiteboard at the other. This guide is written for the second group on their way to the first.

The factors deciding which end a plant sits on are not always size or sector. We have commissioned 200-person beverage plants still running paper batch records, and 30-person specialty producers with full electronic batch records and live OEE dashboards. The difference is usually a board-level commitment to traceability and a control-system partner who treats brownfield work as the default rather than the exception. Pac Technologies' own customer history covers most of that range: Arnott's Biscuits, Capilano Honey, Jack's of Fiji, Nestlé and Smith's Chips among them. None of them are in the same place on the upgrade.

This guide is for the people who decide what to do next. Plant managers and ops directors working out whether their current control stack will get them through the next decade. Engineering leads scoping their first MES. Smaller manufacturers facing a retailer compliance audit with a clipboard and a hope.

Why automate now.

Can you produce a batch record for any pallet in your warehouse within 30 minutes?

If the answer is "give us a few hours," 2026 is the year that answer stops landing well. The decision to automate has rarely sat on a single trigger. It accumulates. A traceability incident no one writes up properly. A labour quarter where two shifts ran short. An OEE figure no one in the room actually trusts. By the time the business case is approved, three or four of those are running at the same time.

Right now there are five, and they fall into three groups.

Pressure 1: customers and workforce both want the plant floor to report itself.

The supermarkets do not call it a compliance program. They call it the supplier portal. Either way, Woolworths and Coles want batch and lot data submitted electronically for higher-risk categories. The penalty for not submitting it begins with the word delisted. Paper batch records do not fit that requirement at volume, and the major retailers do not negotiate it.

At the same time, the workforce that used to plug the data gaps is no longer easy to backfill. More than a third of Australian food and beverage jobs sit in regional communities (AFGC, State of the Industry 2024), where the labour market for shift operators tightened sharply between 2022 and 2025. Plants that ran one operator per machine in 2015 now run one per cell. The keystrokes those people used to provide are not coming back. The line has to produce the data itself.

Pressure 2: management cannot see what is actually happening on the line.

The most common request we have heard since 2022 is some version of: we cannot tell if our line is actually any good. Overall equipment effectiveness (the share of nominal output a line achieves in real running) is the standard answer to that question. A clipboard cannot produce it reliably. Operators logging stop reasons during a shift miss the small stops, round the medium ones, and forget the rest. We have inherited plants where the spreadsheet was treated as the source of truth and had not been reconciled against the clipboard in months.

A SCADA capture, even before a full MES rollout, gives a plant manager numbers they can act on. The reverse is also true. A bigger dashboard does not make a smaller problem. It just makes a worse problem visible faster, which is sometimes the entire point.

Pressure 3: regulators now want data the paper system was never going to produce.

Three regulatory tracks have moved in the same direction at the same time, which is rare enough to notice.

Cyber rules for critical infrastructure (the Security of Critical Infrastructure Act covers the food and grocery sector) increasingly want network segmentation between the corporate IT side and the plant-floor control network. They want asset inventories. They want secure remote access. None of that is doable on a flat-network plant where the controllers and the office printers share a switch.

Food safety enforcement has tightened in the wake of national recalls. Plants whose critical safety checks are interlocked in PLC logic (the line stops automatically when a temperature reading or seal check fails) get an easier audit than plants whose same checks rely on an operator initialling a clipboard. The standards have not changed. The regulator's tolerance for "we usually catch it" has.

Climate disclosure under AASB S2 is becoming a board-level concern for the larger end of the sector, with phased rollout through 2025-2027. The reporting can start from utility invoices, which most plants do. Boards that decide they want better than invoice-level numbers end up asking the engineering team for sub-metering at the cell level. That quietly ends up in the SCADA layer because that is where someone is already collecting tags.

Three regulators. One demand. Plant-floor data in a shape an auditor can read without help.

And the equipment is not waiting.

Under all five pressures sits one inconvenient fact: the controllers many Australian F&B plants run on are being discontinued. Siemens S7-300 PM400 entered active phase-out in October 2023, the PM410 followed in October 2025, and spares are committed until 2033. That is not a long runway when the typical brownfield MES project takes 12-20 weeks to scope and another 24-40 to deliver. Plants that defer the platform decision are quietly choosing to do the whole upgrade in one panicked sprint instead of a planned one.

Each pressure on its own can be deferred. Together they share an answer.

What food & beverage automation actually covers.

"Automation" gets used loosely. In food and beverage it usually means at least three distinct technical layers stitched together: control on the plant floor, supervision and recipe management above it, and traceability/MES tying it all back to the business. Vision systems, weighing systems, and cold-chain logging sit alongside these as adjacent disciplines that almost always come up in the same conversation.

By sub-sector.

Food and beverage is not one industry; it is a half-dozen related ones with very different automation patterns. A dairy MES has almost nothing in common with a craft brewery's batch system except the words on the screen.

Dairy.

Dairy got automated first in Australian F&B. Most of the mature systems are here. So is most of the residual complexity. Multi-silo batch traceability is non-negotiable: silo to bulk tank to pasteuriser to filler to pallet, with raw milk source recorded for every batch. Heat treatment validation under HTST or UHT protocols ties critical PLC interlocks back to public health regulation. Pasteuriser diversion logic must be both deterministic and auditable. Most Australian dairy plants now run some version of an Ignition or Wonderware MES with a SQL-backed batch genealogy, ERP-integrated to SAP or a customer-specific product. The remaining paper-based dairy operations tend to be smaller artisan producers or specialty cheese makers, and these are increasingly the plants asking us to scope their first MES. Dairy was the early mover. The rest of F&B is catching up.

Beverage: canning and bottling.

Beverage automation is dominated by line-speed inspection. A canning line runs 1,000-1,800 cans per minute; a bottling line 400-600. At those speeds, the vision system is part of the control loop. It is not a quality tool that happens to live near the line. Pac Technologies' beverage work has been concentrated in label position verification, fill-level inspection, and date code OCR. Each of these talks to the line PLC for reject sequencing. Filler and capper integration is the second pattern we see most often: closing the OEE loop on the part of the line where most micro-stops occur. The Arnott's Biscuits, Smith's Chips, and Capilano Honey customer references all involve some combination of line vision and filler integration.

Meat and poultry.

Slaughter-floor automation is rare in Australian operations; the regulatory environment, animal welfare considerations, and product variability push the work towards manual processing. Where automation does enter meat and poultry is downstream: cutting and portioning, vision-based grading, labelling, and cold-chain handoff to despatch. Three areas are where the gains repeat. Per-pack traceability tied directly to weight on the label. Vision-based grading that separates premium product. Refrigerated handoff with temperature records that survive an audit. The cold-chain piece is the most underestimated by plant managers. Those records have to hold up at audit time and as evidence in a recall investigation. Paper systems do not.

Bakery.

Bakery is the sub-sector where recipe management does more work than batch control. A typical commercial bakery runs 20-200 product variants; each variant has slightly different mixer times, proofer humidities, oven profiles, and allergen-handling sequences. The interesting control problem is changeover speed: not the recipe execution itself, but how quickly the line can clear allergen-cross-contamination risk between variants. The PLC layer is usually simpler than dairy or beverage; the SCADA recipe management is more sophisticated. Most bakery automation projects we have scoped started with a CIP and changeover sequence audit before any recipe digitisation work began. Most allergen-incident risk in bakery comes from the changeover, not the recipe.

Brewing and distilling.

Brewing and distilling automation sits between dairy (batch-process intensive) and beverage (line-speed dominated). Mash, boil, fermentation, and conditioning each have distinct sequences with different time and temperature integrities. Process-driven versus operator-driven recipe execution is the dividing line we see in scoping conversations. Small craft producers usually want operator-driven, where the engineer of record can override. Large commercial producers want process-driven, where operators follow the recipe the QA team approved. Sustainability reporting is becoming the new driver. Water usage per litre produced, CO₂ recovery from fermentation, energy per batch. Each is a PLC tag that needs to terminate in a board-level disclosure under AASB S2.

Packaged foods.

Packaged foods (biscuits, chips, confectionery, honey, jams, dressings) is where vision systems, allergen control, and format-changeover speed dominate the conversation. Pac Technologies' customer base in this sub-sector reflects the pattern: Arnott's, Smith's, Capilano. Each line typically runs multiple SKUs per shift, and label-claim control (gluten-free, dairy-free, organic certifications) is a control problem before it is a marketing one. Vision systems on every label position, fill check, and seal integrity inspection. Allergen-trace washdown sequences interlocked into the line PLC. The MES layer tends to be lighter than in dairy or pharma-adjacent F&B, but the line-level control logic is dense. Format changeover speed is where engineering investment pays back fastest. Every minute saved on changeover is a minute the line runs.

Standards and compliance: what binds the technical work.

Food and beverage is standards-heavy. FSANZ sets the rules. ISA-88 sets the vocabulary. The retailers set the deadlines. None of it is optional once a plant is supplying the two majors. And the audit, when it comes, looks at what was actually in place on the day of the incident, not at what was on the project plan.

The FSANZ Food Standards Code.

The FSANZ Food Standards Code is the regulatory framework that ultimately constrains plant-floor design. Standard 3.2.2 (Food Safety Practices and General Requirements) sets the baseline every manufacturer works to. Standard 3.2.1 (Food Safety Programs) applies to higher-risk sectors (dairy, meat, eggs, seafood) and brings explicit auditable-programme obligations. Standard 3.2.2A (Food Safety Management Tools), enforceable from 8 December 2024 (FSANZ, Standard 3.2.2A, December 2023), primarily targets food service, catering, and retail rather than manufacturing. The flow-on is that regulators have started applying the same baseline thinking to the suppliers feeding those segments. From a control-system perspective the practical demand is consistent. Time and temperature data integrity. Hygiene-zone interlocks. Records that survive an audit without manual reconciliation.

HACCP and critical control points.

Hazard Analysis and Critical Control Points is the operational framework underneath the FSANZ standards. Every plant has a HACCP plan; the question for automation is which CCPs are interlocked in PLC logic and which are still operator-checked with a clipboard. Migration from clipboard CCPs to interlocked CCPs is usually the strongest single ROI in early-maturity F&B automation work. Pasteuriser diversion logic, metal-detector reject sequences, allergen-segregation washdowns. Each is a CCP that benefits from being deterministic and auditable rather than discretionary.

ISA-88 and ISA-95.

ISA-88 is the batch model that gives MES vendors their vocabulary; ISA-95 is the enterprise-control integration model that ties MES back to ERP. ISA-88's procedural hierarchy (recipe to unit procedure to operation to phase) maps cleanly onto how a batch sequence should be written, regardless of the SCADA vendor. ISA-95's level model (0–4) tells you where each piece of data should live, and which interface it traverses. In our experience, ISA-88 is more invoked than implemented. Most batch systems we audit reference it in their functional design specification without using more than its vocabulary. The discipline pays back when the next engineer picks up the code, not on day one.

GAMP 5, PackML, and the rest.

GAMP 5 applies where pharma-adjacent obligations apply: infant formula, supplements, medical foods. It is rarely needed in mainstream F&B. PackML (OMAC's PackML state model) shows up on packaging lines where the OEM has built it in, and helps with cross-machine OEE consistency. AS/NZS 3000 electrical compliance and AS 4024 machine safety underpin everything. Both should be re-assessed every time the line is meaningfully modified. A separate article on SIL determination in Australia covers the safety side specifically.

From paper batch records to MES: the upgrade journey.

Most plants we walk into cannot. The single most common F&B automation project, and the highest-payoff one, is replacing paper batch records with an electronic MES. The technical work is rarely the hard part. Change management is.

Stage 1: paper.

A clipboard at every critical control point. Operators sign off each batch, and the signed record goes to a filing cabinet, never to be reviewed unless something goes wrong. Stage 1 plants range from 20-person specialty producers to 200-person regional dairies that have been deferring the upgrade for a decade. The costs are real. Operator time (often 30-90 minutes per shift on records alone). Audit risk (paper loses evidentiary value the moment a clipboard is misplaced). Zero trend data (the plant cannot answer "is anything getting worse?" until it actually breaks).

Stage 2: spreadsheet aggregation.

A keyed-in Excel sheet that operators or shift supervisors maintain. Better than paper in theory, often worse in practice. Formulas drift. Files version-fork. The aggregation lies under audit. We have inherited plants where the spreadsheet was treated as the source of truth but had not been reconciled against the underlying clipboard records in months. Stage 2 is usually where a serious recall first reveals the documented batch records do not match what actually happened on the line.

Stage 3: standalone batch software.

A single-vendor batch package, often bundled with the line OEM, that captures batch parameters automatically but does not integrate upstream to ERP or downstream to traceability systems. Workable for simple lines, especially in smaller producers. The limit hits when the plant adds a second line and the data does not move between them, or when retailer compliance asks for batch records in a format the OEM package cannot export. Stage 3 plants typically have 2-3 years of useful life before the limits start binding.

Stage 4: integrated MES.

Per-unit traceability from raw material lot to despatched pallet. OEE captured automatically from PLC data. Recipe management decoupled from PLC code. ERP integration that closes the work-order loop. This is the structural state most large AU F&B manufacturers are operating in, on platforms such as Inductive Automation Ignition, Wonderware/AVEVA, or in some cases a custom MES. Pac Technologies replaced a paper batch system at a feed mill in Beaudesert, Queensland with Silio, an in-house batch management platform. Per-unit traceability runs from raw material receipt to despatched pellet, and the operator-facing layer runs on a tablet rather than a clipboard.

What to look for in your operation.

A quick self-assessment if you have read this far:

• Can you produce a batch record for any pallet in your warehouse within 30 minutes?
• Can the QA team trace a raw material lot forward to every despatched product that used it?
• Does your OEE figure come from a measurement system, or a calculation in someone's head?
• When the alarm goes off, does the operator know what to do without calling someone?
• Has the same data point been hand-keyed more than once in the last week?

If two or more answers are no, the maturity-stage conversation is overdue.

Choosing an automation partner.

Most food and beverage manufacturers in Australia have at least one bad-integrator story. The patterns repeat. A system commissioned and abandoned. Code no one can read. A handover pack that turns out to be a USB stick with the project name on the label. A contract that forces the customer back for every change. The good news is the warning signs are consistent and easy to look for early.

Ten questions worth asking any prospective integrator before commissioning the work:

1. Will you document the existing system before changing anything? Brownfield discipline. The answer should be yes by default, and they should be able to describe what documentation actually means in practice. (See the brownfield upgrade guide for what discovery involves.)
2. Whose coding standard will be used? Theirs or yours, signed off in writing before work begins.
3. What is in the handover pack? Source code, drawings, runbooks, login credentials, network diagrams, alarm response procedures, operator training materials. Everything needed to run the plant without the integrator.
4. How is support priced after go-live? Day rate, SLA-backed retainer, named engineer or pooled response. Each one changes how predictable your support bill is in year two.
5. Are your engineers named on the contract? If the team can change without your knowledge, the contract is not actually about the people.
6. Have you delivered in our sub-sector? "Food" is not a credential. Dairy, beverage, meat, bakery. These are different operating realities.
7. What is the typical project span and price band for work like this? Not a quote. An honest indicative range.
8. What standards do you align to by default? ISA-88, GAMP 5, PackML, AS/NZS. The answer should be specific.
9. Reference customer we can call in our state? Phone numbers, not testimonials.
10. Will the engineers who scope the project be the ones delivering it? Bait-and-switch is one of the recurring patterns in integrator disappointment.

We will not pretend to be neutral on this. Pac Technologies has been delivering brownfield-by-default automation in Australia since 2003. If the questions above are useful, the conversation is worth having. If they are not, the integrator who cannot answer them comfortably is the answer to the next question.
