Quentin Kenihan has died at aged 43 after battling a serious bone disease.

The Adelaide-born actor, comedian and filmmaker was diagnosed with osteogenesis imperfecta at a young age, a rare genetic condition that caused his bones to frequently break.

Kenihan was well-known for his passionate advocacy for people living with a disability, and his unique personality.

At age seven Kenihan rose to fame in the Mike Willesee documentary QUENTIN, which catapulted him into fame.

More recently, Kenihan starred in Network Ten's Quentin Crashes and in Mad Max: Fury Road. Kenihan was also the film critic for ABC 891's breakfast program.

An outpouring of commemorations have flooded social media including a post from friend and star Russell Crowe.

Kenihan was more recently known for running as a candidate for Adelaide City Council where he campaigned for a safer, more accessible council.

On Saturday Kenihan posted on his Facebook page in support of fellow candidate and current Lord Mayor of the City of Adelaide Sandy Verschoor.

“In the race for Lord Mayor of @cityofadelaide I’m throwing my support behind @sandyver. I believe she has the experience & progressive thinking to take #Adelaide to a better future," he said.
