The Australian acting legend was driving alone when he smashed into a tree, prompting emergency services to rush to the scene.
Despite ambulances and cops arriving within minutes, the film icon tragically passed away.
His son Leroy, 49, described his dad as a “legend” and said he was working on upcoming film projects.
He told Daily Mail Australia: “He died in very high spirits and he was very motivated. He was very happy.”
No other details about the accident on Thursday, in New South Wales, have been confirmed.
Page had starred in a series of iconic action movies including several Mad Max films, The Man from Hong Kong, Roadgames, Deathcheaters and Stunt Rock.
He had most recently worked on films Mad Max prequel Furiosa and Three Thousand Years of Longing.
The stuntman came onto the scene in the 1970s and has been honoured in tributes from friends in the industry.
His former manager Brian Trenchard-Smith said yesterday: “Grant Page was Australia’s pioneer stunt performer and my friend for fifty-two years.
“I will miss him terribly. He was an inspiring man, who lived uncompromisingly.
“Most people accept that age weighs upon us, gravity holds us down, death awaits us if we dare too much. Not necessarily, said Grant, as he successfully tampered with the laws of physics and probability.”
Speaking of his skills as a stuntman, Trenchard-Smith said he had an “extraordinary ability”.
“He’s the guy you get to dodge the cars, slide down the cliff on fire, jump into the water and fight the shark.”
One of his most iconic moves was known as the “transfer”.
It saw him climb from the window of a car into another while both were racing down a road at rapid speed.
Page is survived by his four sons, Leroy, Adrian, 52, Jeremy, 51 and Gulliver, 47 as well as his ex-wife Joy and former partner Ulli.
