The NRL has introduced fines for low-grade on-field offences starting in the 2017 season.
Grade-one offences including high tackles, tripping and contrary and detrimental conduct will result in a $1500 fine following a review of the NRL judiciary system.
They replace demerit points leading to possible suspensions, with the changes designed to create a fairer, simpler system and ensure players do not miss matches for minor offences.
However, more serious offences such as dangerous throws, shoulder charges, kicking and striking will still accrue at least 100 points and result in suspensions.
"Where a player is involved in dangerous actions, they can still expect to spend time on the sideline," NRL head of football Brian Canavan said.
