This is bound to stir up the Vic/NSW funding argument when Melbourne is growing faster than Sydney and more cash is going into network in Sydney than Melbourne.  

Assuming this is real and not purely designed to provoke discussion.

Push for PM to commit money to building $20b metro line to Sydney's west

As for the VIC/NSW discussion that is silly since Melbourne is only growing slightly faster and unlike Sydney your rail system is well placed to handle the growth if someone competent was in charge of the rail system. Doncaster aside you have rail almost everywhere it needs to go and a tram system.

Vic is getting plenty of federal money for the airport line ($5 billion) and the geelong fast rail ($2 billion) and yet there hasn't been a single piece of direct federal funding for our new metro lines and Victoria is complaining about too much money being spent in Sydney.
