Australians with questions for US Pilots and ATC's about your airpsace

[Achilles]

In Australia, our airspace is to be 'reformed' soon using the North American Airspace system as a model. Problem is, we don't have anywhere near the amount of Radar, navaids and airports or other aviation infrastructure that the US does. This raises some concerns and questions for pilots and ATC's here. I am hoping that Dunnunda members will post questions here, directly to you guys.

Thanks.
