One year on, Plumbing Detectives investigation still getting results

31 July 2020

Investigations by Queensland’s building watchdog have seen a person prosecuted for offences related to the company Plumbing Detectives Pty Ltd, which was the subject of an earlier Public Warning.

As a result of action taken by the Queensland Building and Construction Commission (QBCC) in January 2019, the Supreme Court ordered an unprecedented injunction to stop a mass mail-out of illegal fridge magnets advertising plumbing services for Plumbing Detectives Pty Ltd.

Prior to this, in July 2018, the QBCC issued a Public Warning against Plumbing Detectives and associated individuals because they did not hold a QBCC licence. This meant they could not carry out, or enter into contracts to carry out, building work, including plumbing, in Queensland.

As a result of the QBCC’s investigations, an individual pleaded guilty earlier this month to one count of unlicensed contracting, and was fined $2,523.

The QBCC found that the individual had performed unlicensed plumbing work at a Carindale residence.

QBCC Commissioner, Brett Bassett, said the result was a warning to anyone considering performing unlicensed building work in Queensland.

“This is especially important with plumbing work, given the important health and safety role played by this trade,” Mr Bassett said.


The individual pleaded guilty in Holland Park Magistrates Court in Brisbane on 3 July 2020 and is unable to be named by the QBCC because no conviction was recorded in this matter.

The unlicensed contracting offence was contrary to section 42(1) of the Queensland Building and Construction Commission Act 1991.
