In the 1992 state election, the Liberals came to power under Premier Jeff Kennett, who planned to cut the costs of Melbourne's public transport network and remove conductors. OneLink were contracted in 1995 to introduce an automatic ticketing system. The tramway union, which opposed this move, went on strike during the 1997 Grand Prix. One month later the government announced plans for privatisation of the PTC. The tram conductors were replaced with ticketing machines between 1996 and 1998—shortly before the system was privatised.
