 On 1 December 2010 legislation was implemented that will see all swimming pool barriers in the state inspected and issued with a compliance certificate by 30 November 2015.Swimming pools be surrounded by a four-sided compliant barrier (using the home as one side of the barrier was outlawed) with a minimum height of 1200 mm (48 inches) from permanent ground level and have non-climbable zones of 900 mm (36 inches) in a 180 degree arc measured from the top of the barrier.For non-climbable zones to be compliant there must not be any objects that are more that 10 mm (0.5 inch) in depth and width in the non-climbable zone.
