Megan Baird's long blonde locks will get the chop in Kotara on Saturday as part of her family's three month-long fundraising campaign for the Calvary Mater Hospital's medical oncology clinical trials.
Honouring the memory of her father Peter Cameron, who was part of the clinical trial before his death in September, Mrs Baird will have her hair shaved off at F45 Training Kotara on December 7 during the gym's open day.
"I am shaving my head to raise awareness for clinical trials in memory of my amazing dad," Mrs Baird said.
"The incredible crew of F45 Kotara is having an open day to show off the new studio and we're raising more funds to donate in dad's name to the oncology clinical trials team of the Mater Hospital."
A GoFundMe was established by the Cameron family in September, endorsed by the Mater, with a target of $10,000. As of Monday, $8020 had been raised.
If the target is reached by December 15, when the GoFundMe campaign will end, the Cameron family will match it dollar-for-dollar, which will go to the Mater's self-funded medical oncology clinical trials.
Mrs Baird said her father was told he had six months to live when he was diagnosed with a rare and aggressive form of kidney cancer cancer, which stopped responding to conventional treatments.
Mr Cameron lived a further 18 months after being added to the clinical trial.
Mrs Baird said the extra time was precious to her family, which she said would not have been possible without the clinical trial.
F45 Training Kotara will be open 9am-2pm. There will be a jumping castle for children, food, prizes, membership specials and short trial classes available throughout the open day.
