Proposed High Speed Rail (HSR)
It may be expensive (the last estimate was $114 Billion with a capital B) however it is needed for the development of our regional centres such as Wagga Wagga, Albury & Goulburn south of Sydney & Port Macquarie, Coffs Harbour, Grafton & Ballina north of Sydney.
The route is proposed to go from Brisbane to Melbourne via Sydney & Canberra. Here is the map below:
I think if the line connected to Bowral, the amount of property developers trying to get a piece of the action there would be absolutely astronomical. It would make Bowral one of the best places to live in the world with an easy 30-minute commute into the CBD.
Here's hoping the NSW government makes an announcement on the route very shortly.
