Gel blasters and other replica firearms will need a reasonable excuse to be carried throughout Queensland after new laws were passed by Parliament.
Changes to the regulation of the popular toys were flagged in February, amid growing concerns from police about their misuse.

The replica guns, which are made of plastic and fire small water-soaked gel balls, are banned in all states except Queensland and South Australia.
Police have not suggested such a hardline approach in Queensland, though the The Gel Blaster Association fear stricter regulation would make the items "essentially unobtainable".
About 700,000 of the blasters are in circulation across Queensland, the association's Chris Sinclair told Nine News.
The amendments to the Weapons Act, which passed Parliament as part of a larger Bill on Thursday, will make it a "reasonable excuse" to possess the blasters if a person is a member of an association.
Recreational activities carried out as part of such a group will also have to occur outside a public place. Further changes are also proposed to classify
"It's not about what they do, it's what they look like," Police Minister Mark Ryan told Parliament. "Replica firearms are not a joke."
LNP education spokesman Jarrod Bleijie said the government had "completely lost the plot when we are regulating toy water pistols".
A petition asking the Palaszczuk government to abandon its plans to regulate the blasters received thousands of signatures during public consultation earlier this year.
The plans came after a number of people were allegedly targeted with the blasters in drive-by incidents.
Other amendments in the bill included changes recommended by the Crime and Corruption Commision's Taskforce Flaxton report into prisons.
These will see new powers to search corrective services staff and compel them to undertake drug and alcohol testing, along with new offences to stop staff interfering with test samples given and ban relationships with inmates.
