The duo’s surprising journey across the outback in a 1930 A-model Ford earlier this year was in the name of Ballarat cancer research. Now they will share exactly how they pulled off the 7000-kilometre mission in documentary East to West.

Take a look at the film trailer below.

O’Toole is set to share more with a Ballarat audience of the drive behind this ambitious adventure, from Byron Bay in New South Wales to Western Australia’s Shark Bay, to raise money for the Fiona Elsey Cancer Research Institute. They went right through the nation’s centre in their beloved vintage car. There will be a special showing of the film in Ballarat Technology Park's Auditorium, featuring a live question and answer with O’Toole, later this month.

O’Toole and McIntosh each lost their mothers to cancer and O’Toole’s brother has cancer. It made their mission personal as they rattled along at average speeds of 40km/h.

“This is without a doubt the hardest thing Keith and I have ever done,” Mr O’Toole told Fairfax Media when they arrived home in April. 

“We’ve been doing a few mad trips together over the years, trips people said couldn’t be done, and we did them anyway...We both like a good challenge and we can put up with each other’s company while tootling along endless roads at a snail’s pace.”

The duo has raised more than $40,000 for FECRI, a not-for-profit organisation, and spread the word in stops along the way about Ballarat’s work fighting cancer with research.

O’Toole has received a Medal of the Order of Australia this Queen’s Birthday for his dedicated service to the retail baked goods industry and Beechworth community. 

Beechworth Bakery has expanded its popular shops across the state, including a bakery Ballarat which opened in 2006.

East to West will show at the Tech Park, home to FECRI, on July 23. Tickets: easttowest.com.au.
