Security Tenders in Australia: How Security Companies Win Government Work (2026)

Government is the largest single buyer of security services in Australia. Courts, hospitals, schools, depots, power stations, and government offices all contract guarding, patrol and surveillance — and it's all tendered publicly. For a security company, these are multi-year, recurring contracts. The barrier is compliance, and it's stricter here than in almost any other category.

Where security tenders are published

Security tenders appear on the federal AusTender portal, the state and territory portals, and the sites of the agencies that buy the most guarding — the courts, the health department, Snowy Hydro, the railways, and the council. TenderWin pulls them all into one daily-synced search, matched to your business:

Live now: security and guarding work from buyers like Overberg District Municipality, the Public Service administration, the Housing Development Agency, and South Australia's Department of Health — the kind of multi-year contracts that anchor a security firm.

The requirements that decide security tenders

Security is a licensed trade, so buyers check the licence before they check the price. The four things that disqualify more security bids than anything else:

• security licensing registration — your company and your guards must be registered with the Private Security Industry Regulatory Authority. An expired security licensing licence ends the bid on page one.
• An active ABN registration (ABN).
• An in-date SME certificate or affidavit for the non-price criteria.
• A verifiable ATO tax compliance certificate — plus WorkCover cover, because guarding is on-premises labour.

What security contracts pay

Guarding contracts run from a few hundred thousand dollars for a single site to multi-million dollar multi-year deployments. Value isn't in the open feed, so the honest pricing guide is the award record — what comparable guarding contracts actually closed at. TenderWin's price-to-win benchmark shows that band for security in your state, built from real award data.

How to win them

• Confirm security licensing, ABN, SME, tax and WorkCover are all current before you price — one lapsed document ends it.
• Price into the winning band; security is scored price + criteria or price + criteria, and the cheapest compliant bid doesn't always win.
• Staff the bid realistically — under-priced guarding wins on paper and fails in delivery.
• Never miss a compulsory site briefing; it's an automatic disqualification.

TenderWin's done-for-you services handle the registrations (ABN from A$950, business registration extract (ASIC) from A$650) and write full bids from A$3,500 — for the contracts you don't want to lose on a licensing technicality.

The bottom line

Security is one of the most reliable government contract categories in the country, and one of the most heavily licensed. The companies that win are the ones whose security licensing and compliance documents are current and who see the tender in time. Both are fixable this week.
