A Sydney to Melbourne Hyperloop ?  

The Age reports that Australian government MP John Alexander is pushing for a high speed rail or hyperloop link between Sydney and Melbourne as a solution to unaffordable house prices - High-speed rail and a Hyperloop: John Alexander's radical housing affordability plan.

High-speed rail between Sydney and Melbourne would be used to decentralise Australia's urban population and open up cheaper housing under a radical plan now endorsed by a parliamentary committee. ... The report also urges the government to monitor and, in future, assess the feasibility of Hyperloop, a supersonic tube conceived by Tesla founder Elon Musk that would potentially see passengers traverse Sydney to Melbourne in less than one hour.

Linking regional centres by rail would enable people to live in Goulburn, for example, and work in Sydney, and ease pressure on crowded city markets. It would "provide an abundant supply of affordable housing for many generations to come", Mr Alexander said.
