Independent Meth & Mould Testing Across Australia

Yes, if you want facts before you commit. Meth residue cannot be seen or smelt, and most states do not require testing before a sale or lease. A professional test with laboratory analysis tells you whether residue is present and how it compares with the national investigation level.

Test Australia collects surface wipe samples to NIOSH Method 9111 from representative rooms, and NATA-accredited laboratories analyse them. Results are compared with the 0.5 µg/100 cm² investigation level in the Australian Government's 2011 Clandestine Drug Laboratory Remediation Guidelines. A result above that level triggers further action. It is not a safe or unsafe line, and some states apply their own requirements.

Not from the level alone. No concentration on its own shows manufacture rather than use. Heavy smoking can leave high residue, and a cleaned lab can leave low residue. An opinion on manufacture rests on manufacture-specific chemical markers and site evidence, assessed together by a qualified scientist.

When manufacture is suspected, Test Australia asks NATA-accredited laboratories to analyse for those markers and records site evidence such as staining, odours and altered fittings. The report explains the reasoning so others can follow it, and sets out a remediation scope for the property and its contents in line with ANSI/IICRC S900, the standard for remediating drug residues.

Not always. Visible mould does not need a test to prove it is there. Testing helps when you need to know the cause, how far it has spread, whether there is hidden growth, or whether a clean worked. A mould assessment answers those questions and finds the water source.

Test Australia inspects for moisture sources, takes moisture readings and collects air and surface samples where they answer a clear question. NATA-accredited laboratories analyse them. The report explains the cause and can include a remediation scope under AS-IICRC S520.

Category 1 is clean water, such as a burst supply pipe. Category 2 is grey water, such as a washing machine overflow. Category 3 is grossly contaminated water, such as sewage or floodwater. Category 2 and 3 water can carry bacteria, and any water left too long can lead to mould.

The category can worsen with time and warmth, and it decides what can be dried and what must be removed under AS-IICRC S500:2025. Testing for bacteria and mould helps when the water may be Category 2 or 3, when materials stayed wet for days, when you need to know a clean worked, or when owners and insurers disagree.

Not until residual contamination has been assessed. Soot, ash and smoke residue travel through a home and settle in rooms, cavities, ducts and contents the fire never reached. A surface that looks clean can still carry residue. Testing by a qualified scientist confirms whether the home is fit to live in again.

Test Australia collects samples across the home and NATA-accredited laboratories analyse them. The assessment follows ANSI/IICRC S700, the standard for fire and smoke damage restoration. The report shows what remains, where, and what needs to happen before you move back in, including which contents can be cleaned and which cannot.

Use a kit for a quick first look and professional testing when the result matters. A meth kit is a 5-minute presumptive screen with a 0.5 µg/100 cm² cut-off. It is not a laboratory result, so confirm any positive with laboratory testing.

Mould petri dishes only show that spores exist, which is true of almost every home. For buying, renting, insurance claims or disputes, use professional sampling with laboratory analysis.

NATA-accredited laboratories analyse every sample Test Australia collects. Test Australia owns no laboratory and is not itself NATA-accredited. Our job is to plan the sampling, collect samples to recognised methods, keep chain-of-custody records and interpret the results in a signed report.

Field work is carried out by Test Australia's suitably qualified occupational hygienists. Test Australia is led by Dan Neil, Principal Occupational Hygienist and Chartered Chemist (MRACI CChem), with 25 years of experience in industrial chemistry and forensic science.

Yes. Reports are written to the rules expert witnesses must follow, so they can be relied on if the matter goes to a tribunal or court. The methods, sample locations, laboratory results and reasoning are all set out, and any other qualified scientist can check them.

Test Australia acts for owners, tenants, landlords, strata managers, buyers and insurers. No report can promise a particular outcome. The report sets out the evidence plainly so decision-makers can weigh it.

Cost depends on the scope. The main drivers are the type of testing, the size of the property, the number of samples, the laboratory analysis needed and travel. Test Australia sends a fee proposal first, then gives a fixed fee for the agreed scope. Reports are available within 5 business days of the laboratory results being received.

A remediation scope or testing after a clean can be added to the same proposal.
