In December 2005, Gower was fired as Panthers captain after incidents at a charity golf event where he argued with several guests, groped the then teenage daughter of former league player Wayne Pearce, chased Mitchell Pearce with a bottle before vomiting on him, streaked nude around the resort, stole and crashed a golf cart, held a butter knife to the throat of a Sydney radio personality before throwing it at resort guests, and engaged in a brawl with resort security before being ejected from the official function and detained by police. He was handed a "final warning" by the National Rugby League and fined A$100,000, with A$90,000 to be paid to an NRL programme encouraging the responsible use of alcohol by league players and $10,000 to replace the destroyed golf cart. Gower was "deeply unhappy" that the Penrith Panthers club did not defend his reputation, and at one stage threatened to "walk" from the club.
