Why Australia needs a leak-detection body
Australia has plumbing bodies, gasfitting bodies and locating bodies. It has never had one for the detection discipline itself: the work of finding a leak precisely, without cutting, before anyone repairs it. The Leak Detection Institute of Australia is being formed to fill that gap: a national not-for-profit standards body for leak detection, covering both water and gas.
The discipline exists. The body doesn't.
Leak detection has grown into a specialised field with its own methods: acoustic, correlation, thermal imaging, tracer gas, moisture mapping, CCTV and membrane testing. The people who do this work well are skilled diagnosticians. Yet there is no dedicated peak body defining what competent, ethical leak detection looks like in Australia, and no consistent way for a customer, insurer or strata manager to tell one technician from another.
Instead, the field sits across eight separate state and territory licensing regimes, each written around plumbing and gasfitting rather than around detection. A technician recognised as competent in one state has no portable credential that means anything in the next. A national insurer engaging technicians across the country has no single standard to point to. The result is a discipline that everyone relies on and no one has organised.
LDIA is being established to organise it: one national standard, one code of conduct and one public register, in a market currently split across eight regimes.
Our mission
To lift and standardise the practice of leak detection across Australia, so that the discipline is recognised in its own right, technicians can prove their competence with a single portable credential, and anyone engaging a leak-detection technician can trust the work behind the mark.
What the Institute does
Accredit technicians and businesses
We assess competence against a defined standard and award the Accredited Leak Detection Technician and Accredited Business credentials: a portable mark recognised across every state and territory.
Set the standard and the code of conduct
We define what competent, non-invasive detection looks like, and we hold members to a written code covering conduct, scope of practice and professional obligations.
Maintain a public register
We publish an open directory of accredited members, so consumers, insurers, strata managers and builders can find a technician whose credentials have been verified, and check that a mark is genuine.
Run training and continuing professional development
We support members to keep their skills current as methods and equipment evolve, and to demonstrate that they have done so.
Advocate for the discipline
We engage with regulators, standards organisations and adjacent trade bodies to argue for the recognition of non-invasive detection as a distinct discipline, and for the harmonisation of Australia’s fragmented state regimes.
How the Institute is being built
LDIA is being established as a not-for-profit body. It is a membership organisation that exists to benefit its members and to raise the standard of the discipline, which means it is not a charity, and it does not seek or claim charitable or deductible-gift-recipient status.
We intend to launch as an incorporated association based in our home state of Western Australia, and the Institute is deliberately designed to migrate to a national company limited by guarantee as membership grows across multiple states. That path (local incorporation first, national structure as the membership justifies it) lets the body form on solid footing without overstating what it is on day one.
The Institute is forming now. It is not yet incorporated, and its governance and tax arrangements will be finalised as part of establishment. We would rather tell you exactly where we are than imply a structure that isn't yet in place.
At a glance
The Institute at a glance
The short version, for anyone weighing whether to get involved. The Leak Detection Institute of Australia is a national not-for-profit being established to accredit and set standards for the leak-detection discipline, covering both water and gas.
It is forming now: not yet incorporated, with no members yet. The founding members are the technicians and businesses who help build it. The detail behind each line here is set out across this page.

A founding principle
A founding principle: members locate, licensed trades repair
The Institute is built on a clear division of work. Accredited members locate leaks using non-invasive methods — they find the problem precisely and diagnose it. They do not carry out the repair, and they do not perform gas pressure or leak testing. That work belongs to licensed trades.
Members locate. Licensed trades repair.
Gas safety
All gas pressure and leak testing and all make-safe work is carried out by a licensed gasfitter, in accordance with AS/NZS 5601.1.
This split is LDIA accreditation policy and professional best practice — a condition of holding the mark, not a statement of the law. It keeps detection precise and non-destructive, keeps repair and gas work in licensed hands, and gives customers a clean, safe handover between the two.
This page provides general information about the leak-detection discipline. It is not legal advice. Licensing and scope-of-practice requirements differ between states and territories and change over time; verify current requirements with the relevant state regulator.
Working alongside the wider industry
LDIA is not here to duplicate the bodies that already serve plumbing, gasfitting and utility locating. We define the detection discipline that sits alongside them, and we work with the broader industry rather than against it.
We engage with the Master Plumbers associations and with NULCA, the National Utility Locating Contractors Association, whose members share ground with leak-detection specialists. We advocate to Standards Australia for a dedicated guideline on non-invasive building leak detection, which does not yet exist. And we engage with state regulators on the recognition of detection as a distinct discipline and on harmonising the requirements that currently differ across every jurisdiction.
These are relationships we are building, and positions we advocate for. We do not claim endorsement, partnership or recognition by any of these organisations, and we will only ever describe such a relationship once it genuinely exists.
Founded to build what was missing
LDIA began with a simple observation from inside the field: leak detection had matured into a genuine discipline, but nothing existed to define it, standardise it or vouch for the people who do it well. The Institute is founder-led and forming now, starting in Western Australia with national scope in its sights from the outset.
Because the Institute is still being established, its first members carry real weight. Founding members help shape the standard they will be held to, lend the body its foundational credibility, and are first onto the public register when it opens. There are no members yet, which is precisely the opportunity. If you detect leaks for a living and want a hand in building the body that represents your work, this is the moment to step forward.
Two ways in
For consumers, insurers, strata managers and builders: find a technician whose accreditation has been verified against a national standard, and learn to look for the LDIA mark.
