HIS 1969 HT Holden model car is polished, prepped

HIS 1969 HT Holden model car is polished, prepped and ready to go as Peter Adams revs up for the ride of a lifetime.

The Bellbird Park mechanic will tomorrow embark on a 10-day action-packed adventure through the outback as part of the XXXX Gold Variety Bash.

Travelling alongside his wife Bernie, Mr Adams, 53, will join a convoy of more than 140 themed vehicles on a 4000km trip from Dalby to Mackay.

The annual event, now in its 23rd year, has become one of Australia's most successful charity motoring events.

Money raised will go towards fundraising for children whose families and carers rely on Variety - the Children's Charity Queensland for assistance.

Visiting 12 schools during the trip, the 'Bashers' - as they are affectionately known - will help deliver much needed equipment to schools and communities along the way.

Mr Adams said he had taken part in the event each year since 2006 and that it was always a great experience.

"Bringing a smile to kids' faces who you are helping really makes the trip worthwhile," he said.

"It's also a great opportunity to meet new people and travel with friends who you've met on previous bashes."

To take part in the event, each entry pledges to raise a minimum of $8000 as a donation to Variety.

Mr Adams, who met his wife during a previous bash, said they had been busy collecting donations throughout the year.

"The community is always very supportive," he said. "We've held meat raffles at Goodna RSL and got sponsorship by Ipswich City Council."

Since inception, the Variety Bash has raised nearly $16 million in Queensland.
