In 2024-25, the Australian Government published 86,926 contracts worth a combined $104.9 billion on AusTender, the highest ever value recorded. Add state, territory, and local government procurement, and the total opportunity across Australia is significantly larger.
But many suppliers still miss relevant contracts, not because the opportunities aren't there, but because they are searching in the wrong categories, or not monitoring the right portals. Understanding how government organises what it buys is one of the most overlooked steps a supplier can take.

How Government Tenders Are Categorised in Australia
The UNSPSC System
Most Australian government procurement systems, including AusTender, use the UNSPSC (United Nations Standard Products and Services Code) to classify procurement activity.
According to the Department of Finance, agencies are required to apply UNSPSC codes to all planned procurement, open approaches to market, standing offer notices, and contract notices published on AusTender.
| Level | Description | Example |
|---|---|---|
| Segment | Broadest category | Information Technology |
| Family | Sub-grouping | Software |
| Class | More specific | Business application software |
| Commodity | Most detailed level | Project management software |
How AusTender Uses UNSPSC
AusTender uses a customised subset of the UNSPSC code set. When you register and set up notifications, selecting a main category automatically captures all sub-categories under it, so you can start broad and refine over time.
The AusTender “What the Government Buys” tool shows contract activity by UNSPSC category across all Commonwealth agencies, a useful starting point for understanding where procurement is concentrated in your sector.
Key Takeaway
Capable suppliers still miss opportunities when their alert settings are too narrow or when they only monitor one portal.
“We consistently see suppliers who are genuinely capable of delivering a contract but never see it because they've set up their alerts too narrowly. Without a systematic approach to monitoring across all portals and categories, relevant opportunities slip through regularly,” says Consolidated Tenders Managing Director, Stephen Blacketer.
While every industry participates in government procurement, not all categories generate the same volume of opportunities. Some sectors see continuous procurement activity due to recurring operational requirements, while others are driven by major infrastructure programs, policy initiatives, or long-term investment strategies.
The Biggest Government Contract Categories in Australia
These sectors consistently generate the highest volumes of opportunity across federal, state, and local government.

Why Suppliers Still Miss Opportunities in Their Own Category
Even experienced suppliers miss relevant tenders. The reasons are rarely about capability. They’re about visibility.
- Categories set too narrowly: selecting only the most specific sub-categories can miss work classified differently.
- Monitoring only one portal: suppliers focused only on AusTender may miss state, council, interstate, and Commonwealth opportunities.
- Not reviewing awarded contracts: awarded contract data can show how agencies describe and classify work in your sector.
“Monitoring multiple portals across different jurisdictions manually is unsustainable for most SMEs. Each portal has its own category structure, its own notification system, and its own timing. By the time a supplier has checked five different portals and filtered for relevance, a significant portion of the response window is already gone. Centralising that process isn’t just convenient. It’s a competitive advantage,” says Blacketer.
How to Choose the Right Categories for Your Business
What This Means for Suppliers
It is often better to start slightly broader, review what comes through, and refine over time than to begin too narrowly and miss relevant work entirely.
- Start broader than you think. Selecting a main category often captures all sub-categories automatically.
- Review how agencies describe your work. Search awarded contracts and note the language agencies use.
- Add adjacent categories. Think about what agencies might procure alongside your core service.
- Register on portals. Set up categories on AusTender, relevant state portals, and an aggregated platform where appropriate.
- Revisit quarterly. Category selection should evolve as your services and market understanding develop.

Visibility is half the battle
Government procurement spans a far broader range of industries than most suppliers realise. The challenge for most businesses isn't capability. It's ensuring they're visible in the right categories, across the right portals, at the right time.
Consolidated Tenders aggregates government tenders from across Australia and New Zealand into a single platform, helping suppliers stay across opportunities from multiple portals and jurisdictions.
