Country music superstar Keith Urban has been unveiled as the special celebrity guest performing at the It's a Bloke Thing lunch.

His involvement in the luncheon comes as no surprise after organisers said the guest had a personal history with the prostate cancer awareness message the event spruiked.

Prostate cancer awareness is an issue close to Mr Urban's heart, with his family having a history of the disease.

His father Robert died after a battle with the cancer in December 2015. His grandfather and several of his uncles also had the disease.
