This is from 2011. Can you Sharks fans remember the incident in question?

How long can the referee play advantage? When was the advantage taken in relation to round 5's Sharks v Sea Eagles game?
The advantage is over when the referee deems the non-offending team has taken their opportunity. This varies from referee to referee. Last year we tried to make the ruling black and white by saying that the advantage is taken when the ball is advanced 10 metres from the point of the infringement. By doing this we were trying to take away the grey area around the ruling.
We changed this after constructive criticism arose last season when teams were passing it from sideline to sideline, but were ruled to have not taken their advantage because of the 10 metre rule we had in place.
In the Cronulla v Manly game, it is unanimous across the referees that Manly did not take their advantage. They did throw one pass, but they didn’t have an opportunity to take advantage and that is why the play was called back for the original infringement.
Ultimately, it is now up to the referees discretion to decide when the advantage has been taken.
