Much of the debate on the subject under this government centred on the Prostitution Amendment Act 2008, introduced in 2007 by Alan Carpenter's ALP Government. As a background, a working party was formed in 2006, reporting the following year. Although the resulting legislation passed the upper house narrowly and received Royal Assent on 14 April 2008, it was not proclaimed before the 2008 state election, in which Carpenter and the ALP narrowly lost power in September, and therefore remained inactive, the incoming Coalition Government having vowed to repeal it in its "Plan for the First 100 Days of Government". The Act was based partly on the approach taken in 2003 in New Zealand (and which in turn was based on the approach in NSW). It would have decriminalised brothels and would have required certification (certification would not have applied to independent operators).
