WA Attorney-General Michael Mischin is not known for getting on the wrong side of the law but even he is prepared to face time behind bars for a good reason.
With other government, industry and sporting leaders, he will be one of next month's Convicts for a Cause at Fremantle Prison.
The fundraiser is organised by the Rotary Clubs of Perth and Mt Lawley, Cystic Fibrosis WA and the Liver Foundation of WA to help cure and care for children with polio, cystic fibrosis and liver disease.
Head organiser Jason Skinner said the clubs had raised more than $160,000 since the first event in 2010. "The response and generosity from the public has been tremendous," he said.
Top executives, government officials, ministers and other community leaders have agreed to be locked up until they raise $500 to post bail for their release.
Mr Skinner said the clubs hoped to raise $150,000 on September 12 with the theme this year being Grand Victorian.
Rotary clubs worldwide are trying to eradicate polio, a highly infectious viral disease that mainly hits young children and can cause permanent paralysis.
The Perth and Mt Lawley clubs are also fundraising for children with cystic fibrosis, an inherited disease that affects the lungs and digestive system. Advances have greatly improved victims' average life expectancy, which was just five years in the 1950s.
The Liver Foundation is raising money to set up a children's liver transplant unit.The fundraiser starts at 6.30pm and tickets are $30. For details go to convictsforacause.org.au.
