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.

UNSPSC is a hierarchical four-level system:

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.

“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. 

MANAGEMENT AND BUSINESS PROFESSIONAL SERVICES

One of the highest-volume categories in Australian government procurement, and where SMEs are highly competitive. Official Department of Finance data shows SMEs win over 51% of contracts in this sector.

Common opportunities include:

• Management consulting and advisory services
• Policy and strategy development
• Program and project management
• Change management and organisational development
• Human resources consulting
• Communications and stakeholder engagement
• Training design and facilitation
• Research and evaluation services

Key buyers:

• Commonwealth departments and agencies
• State government central agencies
• Regulatory bodies and statutory authorities

SME note:

This category is heavily represented on the Management Advisory Services (MAS) Panel, where SME-only invitations apply for contracts under $125,000.

ENGINEERING, RESEARCH, AND TECHNOLOGY SERVICES

A major procurement category driven by infrastructure investment, defence capability, and digital transformation. Official government data shows SME participation rates exceeding 59% in engineering and research services, one of the strongest SME win rates across all categories.

Common opportunities include:

• Civil and structural engineering
• Environmental engineering and assessment
• Research and data analysis
• Scientific and technical consulting
• Laboratory and testing services
• Engineering project management

Key buyers:

• Department of Defence
• Infrastructure Australia
• State roads and transport agencies
• Water authorities and utilities
• Research agencies (CSIRO, ANSTO)

CONSTRUCTION AND BUILDING MAINTENANCE TENDERS IN AUSTRALIA

Active across all levels of government, from major infrastructure to routine trades maintenance. The most commonly produced goods and services by the Australian Government include construction and maintenance services, alongside ICT and professional services.

Common opportunities include:

• Civil construction and earthworks
• Road and pavement works
• Building construction and fit-outs
• Electrical and mechanical trades
• Plumbing and hydraulic services
• Painting and property maintenance
• Facilities management
• Grounds and landscaping maintenance

Key buyers:

• Local councils (high volume of routine maintenance)
• State infrastructure and transport agencies
• Department of Defence (base facilities)
• Health departments (hospitals and health facilities)
• Education departments (schools and TAFE campuses)

SME note:

Local councils and state maintenance panels frequently favour local and regional businesses. Many routine maintenance contracts fall below formal tender thresholds, making panel arrangements particularly valuable in this sector.

IT AND CYBERSECURITY CONTRACTS

Government investment in digital transformation and cybersecurity has made ICT one of the fastest-growing procurement categories in Australia. The Digital Transformation Agency (DTA) alone oversees around $9 billion in annual IT procurement across federal agencies, with over 4,259 approved suppliers on its digital marketplaces as of late 2024.

Common opportunities include:

• Software development and integration
• Cloud services and infrastructure
• Cybersecurity services and assessment
• Managed IT services
• Data and analytics
• Digital transformation consulting
• Network and telecommunications services
• ICT hardware procurement

Key buyers:

• Digital Transformation Agency
• Services Australia
• Department of Home Affairs
• Australian Taxation Office
• State government digital and ICT agencies

SME note:

The DTA’s BuyICT marketplace provides a structured pathway for SMEs to compete for government IT work. The Australian Skills Guarantee also now applies to eligible ICT procurements, creating additional requirements that specialist firms are often well-positioned to meet.

HEALTHCARE AND MEDICAL PROCUREMENT

A consistently active procurement area spanning federal health agencies, state health systems, hospital networks, aged care providers, and community health program, covering both goods and services.

Common opportunities include:

• Medical equipment and devices
• Pharmaceuticals and consumables
• Allied health and clinical services

• Aged care services and supports
• Public health consulting and research

Key buyers:

• Department of Health and Aged Care
• State health departments and local health districts
• Hospital networks
• National Disability Insurance Agency (NDIA)
• Services Australia

Compliance note:

Healthcare procurement often involves strict accreditation, credentialing, and regulatory requirements. Ensure all relevant certifications are current before bidding.

PROFESSIONAL SERVICES: LEGAL, FINANCIAL, AND ACCOUNTING

Legal, financial, and accounting services are procured continuously across government for compliance, audit, regulatory, and commercial advisory functions. Many are structured through standing offer panels, making prequalification a priority for firms in this sector.

Common opportunities include:

• Legal services and counsel
• External audit and assurance
• Financial advisory and modelling
• Risk management consulting
• Actuarial services
• Probity advisory
• Accounting and compliance services

Key buyers:

• Australian National Audit Office (ANAO)
• Treasury and Finance departments
• State regulatory and compliance agencies
• Commonwealth entities requiring external audit

CLEANING, FACILITIES, AND PROPERTY SERVICES

One of the most accessible categories for SMEs entering government work. These contracts are released continuously, are frequently lower value, and are awarded heavily at state and local government level, all factors that favour smaller and regional businesses.

Common opportunities include:

• Commercial cleaning services
• Waste management and recycling
• Security services and monitoring
• Grounds and garden maintenance
• Pest control
• Property and building management

Common opportunities include:

• Environmental impact assessment
• Sustainability consulting
• Contamination assessment and remediation
• Renewable energy project support
• Carbon accounting and reporting
• Biodiversity assessment and offset programs
• Water quality and management

Key buyers:

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 means missing opportunities where agencies have classified similar work differently. A cybersecurity firm may miss work listed under broader digital transformation categories. A training provider may overlook contracts listed under HR or workforce development.

• Monitoring only one portal

Suppliers focused only on AusTender miss state-level opportunities. Those monitoring only their home state miss council, interstate, and Commonwealth contracts.

• Not reviewing award contracts

The AusTender “What the Government Buys” tool shows how agencies classify and award work in your sector. Invaluable intelligence for refining your category profile.

“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

• Start broader than you think

On tender portals, selecting a main category captures all sub-categories automatically. Start wide, but refine based on what you actually receive.

• Review how agencies describe your work

Search awarded contracts on government portals and note the language agencies use. These are the keywords and categories worth monitoring.

• Add adjacent categories

Think about what agencies might procure alongside your core service. A project management consultancy should also monitor program governance and change management. An environmental consultant should check infrastructure planning and sustainability categories.

• Register on portals

Set up categories on AusTender for Commonwealth work and your relevant state portals for state and local opportunities. However, you might find it more efficient to register in an aggregated platform like Consolidated Tenders for comprehensive ANZ coverage without managing multiple logins.

• Revisit quarterly

Category selection is not a one-time task. As your services evolve and as you learn how agencies classify work in your sector, your profile should evolve with it.

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.

Getting your categories right is one of the simplest and highest-return steps any supplier can take.

FREQUENTLY ASKED QUESTIONS

What are the biggest government tender categories in Australia?

The highest-volume categories consistently include Management and Business Professional Services, Engineering and Research, Building and Construction, Information Technology, and Healthcare. These generate significant opportunity across federal, state, and local government.

What is a UNSPSC code and why does it matter?

UNSPSC stands for United Nations Standard Products and Services Code. It's the classification system used by AusTender and most Australian government portals to categorise goods and services. The categories you select determine which tender notifications you receive, making correct category selection critical for visibility.

Can I select multiple categories in AusTenders?

Yes. Suppliers can select multiple UNSPSC categories when setting up notifications. On AusTender, selecting a main category captures all sub-categories under it automatically.

Do state portals use the same categories as AusTenders?

State and territory portals use similar structures but vary in terminology. Suppliers should set up categories independently on each portal they register with.

How often should I review my category selections?

Quarterly is a practical starting point, updating as your services evolve and as you learn how agencies in your sector describe procurement activity.
