They tore up the red earth from Perth to Darwin on two wheels for charity.
But, rather than riding the 5000km in style, top WA male models Ben Hollings and Adam Quigley instead jumped on the back of two faithful Postie motorbikes to make the journey north - 7hp vehicles far more appropriate for delivering mail than cross-country adventuring.
Last month Hollings, of East Victoria Park, and Quigley, of Mt Lawley, set out on their two-week bike trip through the outback to help raise funds for The Fred Hollows Foundation, an organisation committed to improving the health of indigenous Australians and helping prevent blindness.
"The long straight roads with nothing were probably the hardest part of the trip," Hollings, 32, told AAA.
However, the long road trip wasn't a new experience for the Chadwick's Perth hunks, who just last year completed an equally lengthy voyage across India on tuktuks.
"We like the adventure and we thought, let's do something else, something that will keep the adventure going but is a bit different to the India tuktuk trip," Quigley, 31, said.
As part of the preparation for the trip, the duo had to ensure their former Australia Post bikes were well equipped for the journey, even if they were just taped together.
"We had to do a few modifications to them," Quigley explained.
"There's a different petrol tank on them, which is sort of attached by random bolts, bits of an IKEA shelf, duct tape and some doorstops."
When it came to choosing a cause to promote through their adventure, the men wanted the funds raised to go to a charity that was impacting the area they would travel through.
"We thought 'What's a charity that could use some extra funds and that helps people in the remote areas of Australia'," Quigley said.
For Hollings, the trip was also a great opportunity to explore parts of WA.
"I've never really gone by car anywhere north of Kalbarri so going through Karijini was amazing," he said.
"The trip ended up being a bit of a sampler of the outback so there are a lot of places I want to go back and visit."
With a successful end to this journey, the adventures won't be over anytime soon, with another unusual undertaking already in the works.
"We've already got an idea for our next adventure as well," Quigley admitted.
"We'll probably ride petrol-powered skateboards around Tasmania."
