Mr O'Malley and his two daughters, Laura and Karly, left Bondi on Sunday, July 28, and have now crossed the Queensland border.

"We're going really well," he said. "We did have a small setback on the way up to Nowra, but we fixed that up.

"We've just finished at the Miles State School in Queensland. Variety made some donations to their sustainable veggie garden, and we're about to head off on a 600-kilometre day."

The three members of Car 29 are embarking on a long trip to Batt Reef near Port Douglas.

"It's been pretty good so far with the girls," Mr O'Malley said. "They're enjoying all the tracks through the State Forests; there's some really true bash tracks.

"We're talking about family stuff, having conversations about plenty of other subjects, and we've got the music belting away.

"We've also had some impromptu stops along the way. We had a really good stop on day two with a farmer, and it was good to find out what they're up to in that area.

"I was a little nervous about driving with my daughters, but the days have been really good. The girls are socialising really well, and I'm getting a lot of positive comments from other teams.

"It's been really special so far."
