West Leederville-based Giles Partners Chartered Accountants started the Rough Rider Rudling Charity Golf Day in honour of Peter Rudling, who died of prostate cancer five years ago.
Mr Giles said Mr Rudling�s illness was �really aggressive�.
�He had a cracking sense of humour – he would have loved the golf day,� Mr Giles said.
Mr Giles said the West Australian Golf Club in Yokine had hosted the event for four years.
The charity golf day has raised more than $31,000 for the Prostate Cancer Foundation of Australia (PCFA) since 2010.
�We really want to push the awareness rather than the fundraising,� Mr Giles said.
�If five or six guys go and get themselves checked it because of it, it�s a success because there�s no self-assessment for prostate cancer.�
Through registration fees and raffle tickets, Mr Giles said he hoped to raise $15,000 for the PCFA.
Kim Ledger, father of late actor Heath Ledger is a prostate cancer survivor and will be a guest speaker at the event on November 9.
PCFA events and office co-ordinator Amy Ward said men could find it �scary� to have their prostate checked.
�Because it�s not something you can do yourself and you need to see the doctor, a lot of people put it off,� Ms Ward said.
�Also, prostate cancer is not seen as being as sexy as breast cancer. If it�s detected earlier there�s a much better chance.�
