Bowls Australia completed a major overhaul of its National Ranking System in October of 2004. The move followed significant changes to the sport’s national event program and the introduction of the grand prix series.

The ranking system was again updated in 2008 to reflect points earned over a three year period, with points progressively decreasing in value over time. This will begin with points from January 1, 2007.

Under the current system there are individual ranking lists for men and women covering each discipline in the sport — singles, pairs, triples and fours.

Players accumulate points based on their performances in five grand prix events during the season including the circuit's benchmark tournament, the Australian Open.

Bowlers can also earn ranking points by reaching the final of their state championships.

The National Ranking System was designed to ensure that a player’s ranking reflected his or her performances in major events. It rewards strong performances in the most significant events on the Bowls Australia calendar. Good performances in state championships are also recognised, which is important in terms of raising the status of these events.

In 2011, the major events from which ranking points were secured included the Australian Open (February), Queensland Open (July), Australian Indoor Championships (August), NSW Open (September), and all state championships.

The current rankings displayed are for the 2012 Australian Open, while the 2012 Australian Indoor Championships and all state championships will also contribute to this year's National Ranking System.
