minister after Menzies. One of the first programs instigated by the Howard government was a nationwide gun control scheme following a mass shooting at Port Arthur. The new government saw industrial relations and taxation as two key areas of economic reform which had been left undone by the Hawke-Keating governments. The coalition introduced industrial relations reforms in 1996 which promoted individual contracts and enterprise bargaining. In 2006, it controversially introduced the WorkChoices legislation, which made it easier for small businesses to terminate employment. After the 1996 election, Howard and treasurer Peter Costello proposed a Goods and Services Tax (GST) which they successfully took to the electorate in 1998 and implemented in July 2000.
