Cronulla's Todd Carney starred as the Sharks beat Brisbane 19-18 in Friday night's NRL clash at Suncorp Stadium.
In a game light on stars due to State of Origin and injuries, the Sharks five-eighth proved the difference in his 150th first-grade match.
Carney had a hand in all three Cronulla tries and slotted a decisive second-half field goal to heap more pressure on Broncos coach Anthony Griffin.
The Broncos took the lead after a scoreless first half when Josh Hoffman crashed over to end a 167-minute point-scoring drought for the home team.
Carney took control thereafter, sending Michael Gordon and Jayson Bukuya over to put the Sharks ahead.
