A CAMPAIGN targeting illegal firearms has increased tip-offs to police three-fold since its launch on the first day of May.

In just 20 days, Crime Stoppers Queensland was given 69 tips relating to prohibited guns through its 3,2,1 campaign.

That is triple the average number of tip-offs, adding up to about three each day.

The anti-illegal firearms push builds on the momentum of the Queensland Police Service's weapons amnesty which encouraged the surrendering of 18,623 unregistered weapons.

Of those, 1090 were handguns or semi-automatic weapons.

Crime Stoppers Queensland chief executive Trevor O'Hara said the campaign's success showed Queenslanders were serious about demanding safer communities.

"Queenslanders know the dangers of illegal firearms ending up in the wrong hands, and are coming forward anonymously with information to help prevent criminal activity," Mr O'Hara said.

"It's encouraging to see Queenslanders speaking up about illegal activity and we're listening."

Mr O'Hara said unregistered weapons were always dangerous because they were often invisible to police.

"The 3,2,1 campaign places the onus on Queenslanders to make their communities safer and report any information about illegal firearms."

The campaign encourages people to call Crime Stoppers and report any illegal weapons.

Anyone with information about an illegal firearm should contact Crime Stoppers anonymously on 1800 333 000 or go online to http://www.easyas321.com.au
