Online bookmaker sportsbet.com.au has completely swapped the odds for Thursday night’s NRL blockbuster between the Sharks and Broncos.

• Broncos go from $2.00 outsiders to $1.81 favourites v Sharks
• Seven times as much money bet on Broncos to win season opener

Cronulla have gone from $1.80 favourites to $2.00 outsiders, while Brisbane have been backed in from $2.00 to $1.81.

Seven times as many dollars have been invested on the Broncos in comparison to the Sharks.

Punters have deserted Cronulla since Grand Final day with the premiers blowing out from $9 to $15 to defend their title.

“As defending premiers playing on their home ground, we had to put up the Sharks as favourites, but sheer weight of money has turned the odds upside down overnight,” said sportsbet.com.au’s Christian Jantzen.
