In May, Denis' cousin, fashion designer Neville Quist, shared the sad news on social media of his passing. He was battling terminal cancer and had been receiving palliative care at Mary Potter Hospice in North Adelaide.

"My legendary cousin has exited the stage for the very last time," he wrote. "The King of Swing and former Lord Mayor of Unley who opened for Frank Sinatra at Sanctuary Cove has sadly passed away yesterday surrounded by his beautiful loving family.

"Denis was the consummate entertainer who lit up every room with his charm and style."

It's believed Denis' deteriorating health inspired Sheridan to propose to his boyfriend Kurt Roberts in March. The 35-year-old actor had wanted his dad to be around for his wedding, which was scheduled for New Years' Eve this year.

"I said to Kurt, 'If we are going to get married then we should probably do it sooner rather than later,'" he said at the time.
