Premier Dominic Perrottet has defended the progress of the government's planned western Sydney Metro lines, while criticising Labor's election promise to halt work on part of the rail project.
The coalition last month said it was starting the $260 million process of delivering four new Metro lines at Tallawong to St Marys, Westmead to the Aerotropolis near Badgerys Creek, Bankstown to Glenfield via Liverpool, and Macarthur to the Aerotropolis.
Labor, meanwhile, says it will cease the business cases for two of the Metro lines - the link to the new western Sydney airport and Bankstown to Glenfield - if it forms government later this month, citing cost blowouts.
