Venues
The matches of the 2017 NRL finals series were contested at four venues in three different states around the country.

Finals Structure
The system used for the 2017 NRL finals series is a final eight system. The top four teams in the eight receive the "double chance" when they play in week-one qualifying finals, such that if a top-four team loses in the first week it still remains in the finals, playing a semi-final the next week against the winner of an elimination final. The bottom four of the eight play knock-out games – only the winners survive and move on to the next week. Home-state advantage goes to the team with the higher ladder position in the first two weeks, to the qualifying final winners in the third week.

In the second week, the winners of the qualifying finals receive a bye to the third week. The losers of the qualifying final plays the elimination finals winners in a semi-final. In the third week, the winners of the semi-finals from week two play the winners of the qualifying finals in the first week. The winners of those matches move on to the Grand Final at ANZ Stadium in Sydney
