Last time when I checked, the 11km South West Rail Link in Sydney took 6 years to complete. 12 years after Kevin Rudd promised to build NBN for everyone, after billions of tax $ already spent, my places in inner west Sydney and inner south east Melbourne are still not connected to NBN.

If anyone asks me how long will it take to build the Melbourne to Sydney high speed rail, my honest answer would be 30-50 years.
