Fire authorities say backpackers remain at risk from unsafe accommodation more than a decade after the Childers hostel fire tragedy in southern Queensland.
Fifteen backpackers were killed in the Childers Palace Backpackers Hostel fire, south of Bundaberg, in 2000.
The State Government responded by tightening laws governing hostel accommodation.
Operators must ensure smoke alarms are installed and functioning and establish fire safety management plans.
However, the Queensland Fire and Rescue Service suspects residential properties are being rented to backpackers without complying with the laws.
Building approval officer Gary Barwick says lives are at risk.
"A lot of these houses set up are set up for a normal family to live in," he said.
"They are also a concern for other operators who are legitimately setting up their businesses".
He is urging anyone who suspects property owners of ignoring the laws to report them to authorities.
