Five people have been charged after police hunting for black-market gun traders seized more than 100 illegal weapons in Queensland.

Police hunting black-market gun traders in Queensland have seized more than 100 weapons and arrested five people.

The haul, which included silencers, was seized during raids in southeast and central Queensland as part of a state and federal police operation launched in September.

Police executed search warrants at Mount Archer near Rockhampton and Toowoomba, west of Brisbane, and Tweed Heads, on the Queensland-NSW border.

Details of the operation were released on Wednesday.

The most dramatic raid happened on December 2, when officers from Operation Lima Harrington found 98 firearms and a quantity of ammunition at a Mount Archer property.

A further three firearms were found at another Mount Archer property.

Four men and a woman, aged 37 to 69, have subsequently been charged with offences under the weapons act.

Toni Christmas, from the Australian Federal Police, said the operation showed how determined state and federal police were about fighting serious and organised crime.
