From updates on their Facebook page (http://www.facebook.com/aeroacademy) and website (http://www.aeroacademy.com.au/) I've been able to gather that AAA's Robin 2160i VH-IRN and Cessna R182 VH-SFV have participated in the flight.
I've also observed that they have called into Longreach Airport, after calling into the Comeroo Camel Station in Bourke in New South Wales. From Longreach, both aircraft called into Emerald Airport before overnighting at the Whitsunday Airport (WAVE) at Shute Harbour (as shown) on Tuesday 26 August.
On Wednesday 27 August, both aircraft called into Rockhampton and then Hervey Bay (Fraser Coast) Airports before continuing further South - where they encountered some spectacular weather formations!
