THE Brisbane Anzac parade plans of Rockhampton's war re-enactment troop are back on track after a last-minute reprieve.

Fresh from wowing people across Queensland with their eerily accurate portrayal of First World War soldiers this week, 12 members of the Ninth Battalion Australian Imperial Force Living History Unit were on Friday morning set to boycott one of the state's biggest Anzac Day events.

Brisbane parade organisers late on Thursday told troop leader David Bell his men could not carry their rifles if they could fire bullets.

Mr Bell said he was considering withdrawing from the parade.

The unit decided to miss its home-town parade after it was invited to march through Brisbane's CBD as part of this year's centenary of Gallipoli commemorations.

Mr Bell said not bearing arms went against the reason for the unit's existence - accurately portraying soldiers who fought in the First World War.

RSL Anzac planning authority spokeswoman Wendy Taylor told APN Newsdesk unit members could only carry weapons if they had a certificate proving they could not be fired.

The weapons are not disabled so the troop  can use them for gun salutes at war memorial services.

The bullets used are blanks.

The Queensland Inspector of Weapons Licensing granted the troop an exemption late on Friday afternoon as long as they removed the bolts from their guns.

The troop impressed thousands of people this week as its members performed at two to three memorial ceremonies a day during the Anzac troop train re-enactment tour of Queensland.

Mr Bell said his troop was excited at the turn of events.

"We're very very happy that we will be able to march with our weapons," he said.
