Call it forty thousand dollars. Floor space, the build, freight, flights, accommodation, and three people off the tools for a week. For a Series A deep tech company that is a real number, and it is usually signed off on a feeling rather than a plan.
Then the show ends. You come home with a lanyard, two hundred business cards and a vague sense that it went well. Six months later someone on your board asks what it returned and there is no answer in the room.
So the following year you don't go. And a program you were genuinely well suited to gets let to a company that kept turning up.
I have spent fifteen years on the other side of this, running brand and growth for businesses that treated events as either a line item or a lottery ticket. Neither works. What follows is the version that does, adjusted for a market where nobody signs anything in the room.
Why standard event ROI maths fails in defence
Every event marketing guide you will read is built on the same chain. Leads become marketing qualified leads, MQLs become deals, deals close, and you divide the closed revenue by what you spent. Track it weekly. Report it at six months.
That model is sound. It is also useless to you.
In defence, the person you are talking to is almost never the person who signs. The requirement sits with a capability manager. The money sits inside a program with its own approval gates. The contract may well be let by a prime rather than by Defence. And the distance between a good conversation and a purchase order is measured in years.
The fix is not to abandon measurement. It is to measure the thing the event actually produces, which is qualified access, and to hold it against an eighteen month window rather than a two quarter one. Section eight covers how.
Who you are actually there for
Ranked, because founders spend their time in exactly the wrong order.
1. Prime supply chain teams
Thirteen primes currently sit inside Defence's Global Supply Chain Program: Babcock, BAE Systems, Boeing, HII Australia, Kongsberg, L3Harris, Lockheed Martin, Moog, Northrop Grumman, Raytheon, Rheinmetall, Saab and Thales. Under that program each is funded by Defence to run a team whose actual job is to find competitive Australian suppliers and get them into the prime's global supply chain.
Read that again. There is a person at that show whose job description is finding you. Most founders walk straight past that desk because the stand looks corporate and intimidating. Go and introduce yourself. It is the single highest value ninety seconds available to you at the entire event.
2. Capability managers and program staff
The people who own the requirement. They are harder to identify and they do not wear a sign. They are also the reason the show exists.
3. The startups already inside a program
Wildly under-rated. A founder two years ahead of you who has already been through a contracting process will tell you more in fifteen minutes than any panel session, and can make an introduction that actually gets returned. Defence is a referral market wearing a procurement costume.
4. State government, media, investors
Useful. Not why you are there. Do not let them eat your Tuesday.
Not on the list
The general. Founders orbit the most senior uniform in the room because it feels like progress. It is not. A two star officer does not select your sensor. The person who does is probably standing eight feet away with a worse lanyard.
The twelve-month countdown
Tick these off as you go. Nothing here saves, so screenshot it or print the page if you want a record.
Which show, and when
Australia's three majors are biennial and staggered, so in practice you get one genuinely relevant show most years. That is a feature. It means you can prepare properly instead of maintaining a permanent events function you cannot afford.
Land systems, soldier systems, vehicles, land C4ISR, and the supply chains behind them. First time the exposition has been held in Perth.
Air and space. Trade days run Tuesday to Friday with public days from the Friday. Only attend the trade days. The public weekend is a different event wearing the same badge.
Maritime and undersea, shipbuilding and sustainment, naval autonomy. The most internationally attended of the three.
Selection test
- Does the delegation list include the specific programs your technology serves, or only the domain it sits in?
- Are the primes relevant to you exhibiting, and are their supply chain teams attending or just their marketing people?
- Is there a speaking or capability showcase slot available, and is it at a time an actual human will attend?
- Can you name five people you want to meet before you have paid anything?
If you cannot answer the last one, you are not ready to buy the stand. That is not a reason to skip the show. Go as a visitor for a fraction of the cost, learn the room, and exhibit the following cycle with a target list.
What actually goes on the stand
The default deep tech stand is a photograph of the hardware, a spec table, and a founder standing slightly too far back.
Do not put your technology on the stand. Put the problem it solves. The technology is why you are interesting. The problem is why anyone stops walking.
What has to be visible from three metres away:
- One line describing what you do, in words a smart generalist can repeat to a colleague afterwards.
- The capability gap you close, framed the way Defence frames it, not the way your engineers frame it.
- Proof. A trial, a customer, a program, a partner. One credible artefact beats four claims.
- Logos of anyone real you have worked with, with their permission. Primes recognise primes.
What goes on the one-pager, not the wall: TRL, architecture, specifications, IP position, DISP status. All of it matters. None of it earns attention.
Skip the giveaway
An iPad draw will fill your list with people who wanted an iPad. Coffee, on the other hand, works, because it holds someone in front of you for ninety seconds and gives them a reason to stay that is not commercial pressure. Spend there instead.
The conversation you are not ready for
Here is what you will actually be asked, roughly in this order.
- What problem does this solve?
- Who else is using it?
- Can you make more than one? At what rate?
- Are you DISP?
- What is your export control and foreign ownership exposure?
- Who else in this room already works with you?
Almost none of that is about the technology. Founders answer all six with physics, and then wonder why the conversation ended politely.
Build a thirty second answer with three parts. The problem in their language. What changes when you are in the system. One piece of proof. Then stop talking and let them ask. If they ask about the physics, you have won, because they asked.
Never lead with TRL. Leading with a TRL number tells a capability manager you have been coached to speak defence without having anything to say. Have the number ready. Do not open with it.
The follow-up window
This is where the forty thousand dollars is either converted or wasted, and it is almost always wasted.
Same day
A short note referencing the specific thing you discussed. Not a template. Your competitors are at the same show and the first meaningful contact wins the memory.
Two weeks
Something useful. A relevant document, an introduction, an answer to a question they raised. Never the words "just checking in". If you have nothing useful to send, that is information about the quality of the conversation.
Quarterly, for two years
This is a nurture, not a close. Programs move on their own schedule and your job is to still be in the frame when they do. The company that wins the subcontract is often just the one that was still visible eighteen months later.
Measuring it honestly
Split your measures. Report both.
Leading indicators, within 90 days
- Named conversations with people attached to a program you can identify.
- Registrations completed in prime supplier portals, with a named contact behind each.
- First meetings that converted into a second conversation off the show floor.
- Formal capability submissions made.
- Invitations received to industry briefings or program days.
Lagging indicators, 12 to 24 months
- RFI or tender invitations traceable to a relationship formed at the show.
- Subcontract scope offered by a prime.
- Entry into a grant, accelerator or capability program.
The two numbers for your board
Cost per qualified conversation, and what percentage of those conversations are still live at six months. The first tells you whether the show was worth attending. The second tells you whether your follow-up is real or theatre. Most companies are fine on the first and catastrophic on the second.
Worth noting for anyone building a case internally right now: the 2026 Defence Industry Development Strategy, released in July, put an additional $80 million into Defence Industry Development Grants, announced a relaunch of the Defence Export Facility with small and medium businesses specifically in mind, and introduced a new Defence Industry Hub aimed at making the system more navigable for SMEs. The doors are marginally wider than they were. That does not make the room easier to read.
Nine hills to die on
- Never lead with TRL. Have it ready. Never open with it.
- Put the problem on the stand, not the product. The hardware photo can go on the one-pager.
- Ignore the scanner app. Badge data arrives late and tells you nothing about intent. Capture on paper, with the name of whoever had the conversation written on it.
- Chase the capability manager, not the general. Seniority and relevance are different axes.
- No iPad giveaways. You will pay for a list of people who wanted an iPad.
- Sort DISP before you book the stand. Not after somebody asks.
- Follow up the same day or accept that you have donated forty thousand dollars to a convention centre.
- Do not let anyone measure this in closed deals inside eighteen months. Agree the window with your board before you go, in writing, so the conversation is already had.
- If you cannot say what you do in one sentence a non-engineer can repeat, cancel the stand. Fix that first. It is cheaper, and everything above depends on it.
The pattern underneath all of it
Every failure mode in this playbook is the same failure wearing different clothes. The stand, the conversation, the follow-up, the board report. In each case a company that can do something genuinely valuable cannot make that value legible to the person in front of it.
I call it the commercial translation gap. It is the distance between what your company can do and what the market understands it can do. Deep tech founders are usually exceptional at the first part. The gap is where the value leaks out, and at a defence expo it leaks out at roughly a thousand dollars an hour.
Close the gap and nothing about your technology changes. Everything about how it is received does.
