Raiders stars are up for a dunking on Saturday to help raise money for families affected by cancer.
It looks set to be a chilly exercise for David Furner, Terry Campese, Tom Learoyd-Lahrs and the boys, with the temperature forecast to reach only 22 degrees on the day.
The team has volunteered to be targets on the dunking machine at the carnival to mark the end of the Convoy for Cancer Families.
About 220 trucks and 70 motorbikes - including a couple of Vespas - will take part as the convoy returns to Canberra after an absence of several years.
The trucks from the ACT, Wollongong, Goulburn and Bega are being marshalled by the ACT Eden Monaro Cancer Support Group.
The convoy will assemble in Mitchell before heading down the Gungahlin Drive Extension and Tuggeranong Parkway before pulling into the fair to be held opposite Bunnings in Tuggeranong.
On Thursday the organisers will conduct an auction for the right to be lead truck.
Up to $10,000 has been paid by a truck owner in previous years to lead the convoy in Canberra.
A recent cancer convoy in Wollongong raised $110,000 through an auction by truck owners for the privilege to lead the cavalcade.
Convoy organiser Melissa Gardiner said on Tuesday the support group's office in Queanbeyan was being inundated with inquiries as the date for the convoy drew closer.
''The carnival is going to be a family day, with stalls and games and six local bands that are donating their time,'' she said. ''We will have a raffle where the first prize is a three-day P&O cruise for two people.''
The Raiders say Furner knows too well an NRL coach's head is on the chopping block if the side is not travelling well.
"People have been taking pot-shots at me for the past few years so here's a chance to come along and dunk me in a water tank to raise money for a great cause," Furner says on the team's website.
