It was introduced after the fatal stabbing of NSW teenager Jack Beasley during a night out on the Gold Coast in 2019 drew national attention.

A version of the trial started in 2021, when police were given the power to scan people without a warrant at two precincts on the Gold Coast. The trial was later expanded to include several other public places.

“Knowing that his legacy is helping save lives and spare other families from that pain gives us strength,” Brett Beasley said.

What do the expanded laws mean?

During the trial, police had been able to use handheld metal detectors to seize concealed weapons in “relevant places”, including shopping centres, retail premises, sporting and entertainment venues, licensed venues, and rail lines.

That authority has expanded under the new laws, permitting police to search for weapons in any public area.

What were the results of the trial?

“Jack’s Law is a proven deterrent, and more than 3,000 arrests shows just how critical it has become in modern policing,” Queensland Police Minister Dan Purdie said.

Are there any concerns about the laws?

A Griffith University review of the initial phase of the trial released in August 2022 found that while wanding had contributed to increased detection in one of the precincts, it suggested the practice only be targeted at areas where data shows a proportionately higher prevalence of knife offences.

“There is some evidence of inappropriate use of stereotypes and cultural assumptions by a small number of officers in determining who to select for wanding,” it said.

Do other states and territories have similar laws?

Tasmania passed laws allowing wanding last month, while Victoria recently banned machetes and expanded police search powers.
