Meikleour - Airservices Australia has just spent a fair bit of time and money removing lots of navaids to leave only the Backup Navigation Network, so this might have been practical in early 2015 but it is less practical now. The nearest VOR to Sydney looks to be Canberra, roughly 130NM away, and almost exactly halfway to Melbourne where they ended up. The idea behind the Backup Navigation Network is that all IFR aircraft will primarily rely on GPS for navigation, with only a skeleton network of ground based aids left. Luckily all the GPS-based navigation systems as seen here are so robust!!
