Hat tip to Legal Practice Intelligence's twitter stream for this info...
Legify.com.au is a legislation search tool that finds current government versions of legislation in every state.
It searches only through titles, but makes comparative research pretty easy.
Looking for legislation in other states dealing with criminal procedure? Search under 'justice' for Justices Acts; 'procedure' for procedure acts; etc.
It links instantly to the government sites, saving trouble of even finding them in the first place.
