A motorcyclist was killed during the Australian Historic Road Race Championships north of Brisbane on Sunday.
Rider Steve Anderson, 46, was racing at Lakeside Park at Kurwongbah when he collided with another motorcyclist about 4pm.
“Two motorcycles were entering the main straight and have collided and lost control,” a police spokesman said.
Mr Anderson was pronounced dead at the scene.
Motorcycling Australia said it would investigate the fatal crash, alongside police.
“Anderson received immediate treatment from medical staff at the track,” MA said in a statement on its website.
“MA and Queensland Police are now both investigating the incident. MA would like to express their sincerest condolences to the Anderson family and friends.”
Mr Anderson’s bike had passed pre-race safety checks, the police spokesman said.
Four other riders were injured in separate crashes on the race track on Sunday.
One rider suffered a fractured collarbone and was taken by ambulance to the Royal Brisbane and Women’s Hospital, while another suffered a chest injury and was taken to Redcliffe Hospital.
A 50-year-old man suffered an arm injury in another crash about 12.30pm and was also taken to the Royal Brisbane and Women’s Hospital.
And a 25-year-old man was taken to hospital as a precaution after he complained of back pain following a crash about 2pm.
The Historic Road Racing Championship affords motorcycling enthusiasts the opportunity to race their restored road bikes, according to the MA website.
