For families inspecting a rental, mould, leaks and poor ventilation may be obvious warning signs. Methamphetamine contamination is far harder to spot. Growing awareness of contaminated rental properties across Queensland is prompting questions about what tenants can know before they move in.

The issue has a direct connection to Zillmere, where one rental property became so severely contaminated with methamphetamine residue that it ultimately had to be demolished. The property was found to have methamphetamine contamination after it had been occupied by tenants. Several cleaning attempts followed, but the contamination returned, eventually leading to a lengthy dispute with the insurer.
When a clean home is not necessarily clean
The Zillmere property was intended to become the owner’s home after it had been used as an investment property. Instead, repeated contamination prevented that plan from going ahead. The insurer ultimately agreed to pay the property’s full insured value during the dispute resolution process.
The case comes as specialists in Queensland report treating more homes affected by methamphetamine residue. One specialist told recent media that ordinary bond cleaning and repainting are not enough to remove contamination, with professional remediation costing between $10,000 and $30,000 depending on the property.
The potential impact on children has also emerged as a concern. One family in Queensland initially suspected mould was affecting their 10-year-old child. Testing later identified methamphetamine contamination in the home.
What are renters told?
Queensland currently has no specific legal requirement for landlords to disclose a property’s history of drug contamination to prospective tenants, according to the Real Estate Institute of Queensland.
The Residential Tenancies Authority also does not maintain a register or watchlist of properties known to be contaminated.
That does not mean rental providers can leave a contaminated property in an unsafe condition. The RTA says rental properties must meet requirements covering liveability, repair and relevant health and safety standards. Where drug contamination affects a property’s condition, remediation may be necessary.
For someone inspecting a rental, however, there is no publicly available contamination register to check before signing a lease.
Calls for a contamination register
The absence of such a register has fuelled calls for greater transparency, including proposals for mandatory testing and a system recording properties with a known contamination history.
Supporters of those measures argue they could give prospective tenants more information before committing to a home.

Queensland Health advises that contamination from illicit drug activity can remain in a property and says appropriate assessment, cleaning, and post-clean-up testing may be required. For renters in Brisbane, the Zillmere case puts the issue close to home. It also demonstrates the difference between a property’s appearance and its history.
A freshly painted rental may look reassuring, but paint and a standard clean do not establish whether methamphetamine contamination has previously occurred. The debate now centres on how much information prospective tenants should be able to access before making one of the biggest decisions a family can face: where to live.
