This guide walks through a complete tender from first sighting to submission, with realistic time estimates for each step. It's written for a builder who's never bid on a government or council job before. Pick a real open tender and do the exercise alongside — you'll learn more in two hours of this than reading 20 blog posts.
Start on the portal that's most relevant to your trade + location: buy.nsw for NSW state work, QLD eTender for Queensland, AusTender for federal, or VendorPanel for the ~400 councils that use it. Our live feed at /tenders aggregates all of them in one place.
Filter by your state and trade. Sort by close date — aim for tenders that have 3+ weeks remaining so you have time to do them properly. Read 10–15 titles + short descriptions. Shortlist 2–3 that look like a genuine fit.
For your first tender, pick something ~25% below your typical job size and comfortably within your trade expertise. Don't stretch — you want to learn the process first, then scale up.
Click into the tender detail page. You'll find a documents section with a download link — often a single ZIP containing 10–30 files. Download it all. Most government portals let you download anonymously without a login (NSW buy.nsw, QLD eTender). Some require free registration (VendorPanel, TenderLink). A few require a supplier account (ICN Gateway, some TenderLink listings) — skip those for your first go.
Unzip into a folder named after the tender reference number. Open the RFT main document and skim all 40–80 pages. Don't read in detail yet — just get a feel for what's in the pack.
Before you spend another hour on this tender, answer 6 questions:
If you answered yes to all six, proceed. If not, stop — save the time for a tender where you can win.
Not every tender is worth bidding on. Small-to-mid builders who bid on everything end up with a 2% win rate and burned out estimators. Builders who bid only on tenders they can win have 20–30% win rates and healthy pipelines.
Open the RFT document. Find the section headed something like "Evaluation Criteria" or "Assessment Criteria". Copy it into a Word document — this becomes your response outline.
Next, find every mandatory requirement. These are conditions that will automatically disqualify you if not met. Usually listed in a "Mandatory Requirements" or "Eligibility" section. Common ones:
Tick each one off against your company profile. Any gaps = you don't bid. Missing even one mandatory requirement means your response is rejected without being scored.
If the RFT has a mandatory site visit, attend it — there's no way to bid compliantly without attending. Even if it's optional, go anyway. You'll see things that don't appear in the documents (access constraints, existing services, ground conditions, neighbouring operations) that directly affect your price.
Bring a notebook, camera, and measuring tape. Write down every question you have. Ask the contact officer at the site visit — answers get shared as addenda with every bidder. Don't ask questions that reveal your pricing approach, but do ask anything that would change the scope.
Most RFTs allow written questions up to a cut-off date (usually 5–7 days before close). Submit any clarifications you need — missing spec information, ambiguous scope boundaries, anything unusual in the contract conditions. The agency's answers become binding addenda.
Use the required response structure from the RFT — not your own headings. If they say "Section 3.1 Methodology (max 2000 words)", your response needs exactly that heading and must stay under 2000 words.
For each evaluation criterion, write content that explicitly addresses the criterion. Start every section with "We demonstrate [criterion] through…" so evaluators can tick the rubric as they read. Don't make them hunt for the evidence.
Core sections almost every AU government tender expects:
Use the agency's pricing template. If they give you a Bill of Quantities with fixed quantities, price each line item using your rate book. If it's a lump sum, build a first-principles estimate and document your assumptions. If it's a schedule of rates, apply your unit rates to each item.
Include allowances explicitly: contingency (3–8% is typical), preliminaries, overheads, profit margin. Don't forget GST — government tenders are always quoted ex-GST with GST stated separately.
Most tenders require 5–12 attachments. Standard list:
Before you submit, run through the compliance checklist one more time. Cross-reference every mandatory requirement to where you've addressed it. Cross-reference every evaluation criterion to the section of your response that covers it. Cross-reference every returnable schedule to the filled-in copy in your submission. One missing schedule and you're disqualified.
Have someone who didn't write the response read it fresh. Their job: pretend to be the evaluator. Can they tick every criterion off the rubric without hunting? If not, fix it.
Upload to the portal (or email, depending on the RFT). NEVER leave submission to the last hour — portal outages, file size limits, connection drops, and personal mishaps have cost thousands of bids. Aim to have everything uploaded at least 24 hours before deadline. Check the confirmation email + portal status after upload.
Evaluation takes time. Don't chase the agency — the contact officer can't discuss your specific submission during evaluation. You'll receive either an award letter or an unsuccessful-tenderer letter with reasons. Always accept the debrief when offered — it's the single most useful feedback you'll get for your next bid.
Once you've got a reference project, the next ones get much easier. BidAlert helps you find the right ones to bid on, extracts every mandatory requirement automatically, and drafts your response sections from your company profile.
