How to Become a Supplier to Victoria's Big Build Projects

There is no single application for Victoria's Big Build. To become a supplier, you do three things:

1. Track the packages that match what you make or do.
2. Register on the supplier databases the program points to.
3. Get in front of the people who control each package.

For a tier 2 supplier, those people usually work for the contractor or consortium holding the package. They are rarely at the government authority whose logo is on the site hoarding.

The Big Build's own procurement page names three places to register. The first is the ICN Gateway, run by the Industry Capability Network. The second is the Construction Supplier Register, if you are a construction business. The third is the set of Victorian Government tender websites (Big Build construction procurement page). Do every one that applies to you.

Then accept the limit of a register. It makes you findable to someone who is already searching. It does not put your name in front of the procurement lead choosing a supplier for next quarter.

Outreach does that job. Cold email and LinkedIn run side by side put your name in front of the procurement lead directly, which a database listing cannot do.

What follows is the route for a Melbourne or regional Victorian supplier, step by step.

Who are the buyers behind the Big Build brand?

Big Build is the name of a program. The procurement page describes partners ranging from large construction, manufacturing and engineering firms to small local businesses. Underneath the brand sit several buyers at different levels.

"Becoming a supplier" means winning a subcontract or a purchase order from one of them. If you mix up the levels, your capability statement goes to inboxes where nobody can buy.

Most tier 2 suppliers will never sign a contract with the authority. Your paper will be with the package holder or with one of its subcontractors. Your real competitor is the supplier that package team already knows.

That is where a Victorian business has an edge. My rule is to go after a local audience whenever possible, because buyers open up faster to someone working in the same city. Say you run a fabrication shop in Dandenong. Writing to a Melbourne package team, you start with something an interstate supplier cannot copy: being close to the work.

Which Big Build projects and contractors should you track?

Suburban Rail Loop East is the clearest live example of how the money moves. In December 2025 the Premier announced the project's largest contract. The $6.7 billion Linewide package went to the global consortium TransitLinX, and it includes 13 four-carriage automated trains to be built in Dandenong. The Premier's office says it is the first time trains of this kind will be made in Australia. The contract is expected to support more than 300 small and medium businesses across its supply chain (Premier of Victoria, December 2025).

That number is the reason to track package holders. Hundreds of smaller businesses will supply one consortium, and the consortium decides which ones. The holder builds that supply chain after award, so keep relationships with package teams alive after the announcement instead of treating it as the end of your chance.

SRL East is split into separate packages. The Auditor-General's report, finalised in mid-2026, lists the two stations packages as unsigned and still in procurement. WPF covers the three northern stations at Box Hill, Burwood and Glen Waverley, and SRLA did not expect to award it before August 2026. WPE covers the southern three at Monash, Clayton and Cheltenham, with award not expected before the first half of 2027 (Victorian Auditor-General, Delivering Suburban Rail Loop). The August 2026 date for WPF has now passed, so check with SRLA whether it has been awarded, and to whom, before you plan around either package. If your yard or workshop is in the east or southeast, put those six suburbs in your targeting.

The same report also shows how far dates slip. At the time of the audit, it found that:

• Procurement for the stations packages was delayed by around one year.
• The Linewide contract was signed 17 months after its target date.
• The state was short of confirmed funding to sign the WPE contract.

The practical reading for a supplier: do not plan a quarter of revenue around one award date. Packages that are "about to go to market" can sit there for a year. Build your list from packages already awarded, and keep the delayed ones on a watch list.

The package holder matters more than the program brand. A capability statement that says "suitable for Big Build projects" leaves the reader to do the matching. One that names the Linewide package, the scope you can supply and your distance from the work does the matching for them.

How do Local Jobs First rules change the path in?

Local Jobs First sits in legislation. The Local Jobs First Act 2003 makes two policies legally binding. One covers industry participation (VIPP), the other covers skills on major projects (MPSG).

The official documents work at three levels:

• The policy document sets out obligations for both the agencies buying and the suppliers delivering.
• The Supplier Guidelines bind every supplier on a government project where Local Jobs First applies.
• The model clauses must be written into the documents agencies take to market and into the final contract. There are separate clause sets for Standard projects, Strategic projects, each with or without the MPSG, and for grants. The current set was updated on 1 July 2026 (Local Jobs First key documents).

Strategic Projects also carry a number. In a 2017 announcement of its Forward Plan, the government said it sets a minimum local content requirement for each Strategic Project. Its example was 82% for stage two of the Melbourne Park redevelopment (Premier of Victoria, August 2017). Check the tender for the figure that applies to your package.

Here is why this matters to a tier 2 supplier. The clauses land on the contractor that wins the package. That contractor then carries local participation commitments, and part of meeting them depends on who it buys from. So your local content is something the package team needs, and you should present it as help with their commitment.

A worked example, for an illustrative steel fabricator:

• Weak line: "Victorian owned and operated, quality products, competitive pricing." Every supplier on the shortlist can write that.
• Stronger line: "Fabricated and finished in our Dandenong workshop, a short drive from the Clayton precinct, by a crew employed in Victoria. We can give you the local content share item by item for your commitments."

The second line gives a buyer a reason to pick up the phone. It answers a question the package team has to answer anyway.

Before you write to anyone, run this checklist:

1. Confirm that Local Jobs First applies, and whether the project is Standard or Strategic.
2. Read the model clauses in the tender, or ask to see the relevant terms in the holder's subcontract.
3. Collect your evidence: where the item is made, how many people you employ in Victoria, and what share of each item is local.
4. Write a local content line for that specific package, in the package team's terms.

This is not legal advice.

Where do suppliers register first?

Work through the registers in this order:

1. ICN Gateway. Register and fill in your areas of interest and capabilities properly, as the Big Build page asks. The 2017 announcement above also pointed local businesses aiming at government work to the Industry Capability Network.
2. Construction Supplier Register. The Big Build page sends construction businesses here as well.
3. Victorian Government tender sites. Buying for Victoria is the state's procurement hub. It lists tenders, supplier panels, registers and coming opportunities. It also covers the Digital Marketplace and Supplier Hub, and has a route to apply for state contracts, panels and registers. The same site warns suppliers about phishing aimed at government contractors and suppliers. Treat any surprise "tender invitation" with suspicion until you have checked it.
4. Industry events and briefings. The Big Build page suggests watching for project briefings, which is where package teams appear in person.

There is no single portal for all Big Build work, so plan to keep several registrations current. Use this table to decide where to start:

Registration will not give you names, though. You need a target list of package holders and the people inside them. The checks for whether a B2B lead list is worth sending to apply here.

Who inside the package holder should you contact?

I start every list the same way: go back through your old jobs and work out who really made the buying call on each one.

Then I search with the job titles people in this niche actually hold, never a generic "manager" title, because "manager" will not find the person who signs off your scope.

For a Big Build package, search LinkedIn for the consortium or contractor name together with these titles:

• Package manager or package director for the scope that would use your product
• Procurement lead or procurement manager on that package
• Industry participation manager, the title most likely to care about your local content line
• The engineer or design manager who approves the technical specification for your item

The authority still has a role. Its briefings and announcements tell you when packages move, and its people can confirm who holds a package. But for tier 2 work, you learn timing from the authority and you win orders from the package team.

A worked example. Take an illustrative cable support manufacturer in Melbourne's southeast aiming at the Linewide package:

1. Package and holder: Linewide, held by TransitLinX.
2. Find the people: search TransitLinX on LinkedIn, filtered to Victoria.
3. Shortlist: pick three titles, for example a systems package manager, the procurement lead and the industry participation manager.
4. Map a likely chain: the engineer specifies the item, procurement runs the quotes, the package manager approves, and the industry participation manager counts the local share. Treat that chain as a hypothesis, and let the first replies correct it.
5. Order of contact: start with procurement and industry participation, because both can say "send us a quote." Bring in the engineer once you have a specification question worth asking.

Three people per package is enough to start.

How should a Victorian supplier approach the buyer?

Open on LinkedIn, then follow with email. My rule is simple: the email never goes first. I want it to land with someone who has already seen my name on LinkedIn. Treat the two channels as one follow-up sequence across LinkedIn and email rather than two separate efforts.

I also have Australian numbers for this channel. For an Australian advertising agency, my team ran LinkedIn outbound for 12 months: 37.9% of connected prospects replied, and the full engagement booked 2,582 sales calls.

Expect a background check before anyone replies. No buyer says yes because of one email; they say yes after checking you out. In my experience the deal is mostly decided online, well before anyone gets on a call.

A procurement lead who gets your connection request is likely to look at your profile, your company page and your website before replying. So the work on your LinkedIn profile comes before your first message. At minimum, the profile should show:

• A headline that says what you supply and where you make it
• One project with a real number in it
• A photo or spec sheet in the featured section
• A company page showing a Victorian address

The first email should sell a short meeting, not your whole product range. Then put past projects and results inside the messages themselves, so the buyer sees relevant evidence without having to ask.

The first three touches, in order:

1. Touch 1, LinkedIn. Send a connection request with one line naming the package and your item. For example: "I supply cable support systems from our Dandenong plant and follow the Linewide package. Happy to connect."
2. Touch 2, email after they connect. Keep it to three or four sentences: one similar job, your local content line, and one ask, a 15-minute call to see whether your item fits a coming scope.
3. Touch 3, second follow-up. Send project evidence: a site photo, the spec sheet, the local share for that item.

What should a supplier do in the next 30 days?

Days 1 to 5: pick your lane. Choose one lane where your product clearly fits. Do not try to cover the whole program; the same thinking applies as picking the market before writing outreach. Then list 10 packages that use your item, mixing the awarded Linewide package with other Big Build transport packages that already have a named holder.

Days 1 to 10, in parallel: register. Finish any registrations still missing, in the order from the registration section.

Days 6 to 12: build the list and the proof. Name 3 people per package, which gives you about 30. Verify every email address before sending. If two people in your company sell, split the packages between them so no buyer hears from you twice. In the same week, have these ready before the first send:

• An updated profile
• One project with a number in it
• Your local content line for each package
• Spec sheets in a form you can attach

Days 13 to 30: start the outreach. Send LinkedIn connection requests first, then the email follow-ups. Give each person several touches across both channels, and keep the emails short and plain.

When to stop and reset. Suppose all 30 people have had the full sequence and nobody has replied. Thirty is a small sample, so treat this as a quick check, not a verdict on the market. Do not add 30 new names with the same message. Check three things first:

1. Are these the right titles for the decision?
2. Is the package actually buying your scope now?
3. Does your local content line answer a commitment the holder has?

Fix whichever one fails, then run the sequence again.

If the titles or the local content line for a Big Build package are holding you back, book a call and I will review them with you.
