Looking for tenders in Adelaide and across South Australia? You’re not alone. Finding the right opportunities can feel overwhelming but it doesn’t have to. This guide shows you where to look, what platforms actually work, and how to set yourself up for success.
If you're a business owner or bid manager in South Australia, here’s your heads-up: now is the time to double down on tendering opportunities across Adelaide and the regions.
Strategic procurement planning is well underway, and a steady stream of RFx (Requests for Tender/Quote/Proposal) are being released by South Australian Government departments, councils, and agencies. Whether you're in infrastructure, services, training, tech, or consulting, there’s opportunity here for you.
Start with SA Tenders and Contracts. In South Australia, one portal does most of the work. It carries state government opportunities and a lot of council work too, so it is less fragmented than the eastern states. The City of Adelaide and Onkaparinga, for instance, point suppliers straight to it. Register for free and set several category alerts rather than one narrow keyword.
One South Australian rule shapes larger bids more than anywhere else. The South Australian Industry Participation Policy scores local benefit directly. Over $220,000 you submit an Industry Participation Plan, and above $550,000 it carries at least a 15% evaluation weighting, stepping to 20% on construction over $50 million. Spell out your South Australian jobs, local spend and regional investment. Note that counting as a local business means an operational base in the state and a mostly South Australian workforce.
Where to find current and upcoming South Australian tenders:
- State Government and much council work (tenders.sa.gov.au)
- Local council RFQs and panels via VendorPanel, moving to Unimarket through 2026
- Aggregators of public and private sector tenders

Two things worth knowing before you start. Most council work shows up on SA Tenders and Contracts, but some Adelaide councils, like Port Adelaide Enfield, run procurement through VendorPanel. VendorPanel is moving to Unimarket through 2026, so keep an eye on both during the changeover.
A word on what drives this state. Defence and big infrastructure are the engine here. If you supply into defence, register with the SA Defence Hub on ICN and keep your capability profile current, since much of the work flows through primes rather than open government tenders. And watch the SA Project Pipeline on ICN for early warning on jobs like the North-South Corridor, the new Women's and Children's Hospital and the Whyalla hydrogen work, so you can target owners and head contractors before packages reach the market.
If you want to look for not for profit or private/public company tenders, you are going to have to hustle. They are not bound by any legislation to publicly advertise their opportunities, so the only way to break into them is through good old-fashioned new business development. Research the person to speak to, get an introduction / call them up, make an appointment, find out their needs etc etc.
But let’s be honest. An opportunity comes up, you learn about it, you put a bid in. That’s still no guarantee of success.
Most businesses miss out, and it’s rarely a qualification problem. They:
- Submit cookie-cutter bids,
- Miss critical compliance details,
- Or don’t understand how tenders are really evaluated.
If you’ve lost tenders to “better-prepared” rivals or for reasons unknown, you’re not alone. Many South Australian suppliers are operating reactively by pulling together bids at the last minute, under pressure, with no strategy behind the submission.
What actually works:
- Positioning before the tender is released,
- Strategic go/no-go filtering,
- Clear, direct answers that map to evaluation criteria (not "blah blah aren't we good"),
- And strong local presence that de-risks your offer for buyers.
Most South Australian agencies also publish procurement plans, contract expiry timelines and awarded contracts, which is perfect if you want to plan your BD cycle 12 to 18 months out. Search the awarded contracts on SA Tenders and Contracts and AusTender to see who holds the work and when it comes back to market.
