The RAAF Facebook page contains a full Australia-wide list, and advises everyone that "Please note that flypasts have been allocated based on available resources, and are subject to operational and weather considerations. All activities and times are subject to variation."
Incidentally, local plane spotter Micah S reports that three Australian Army Commonwealth CA-32 (Bell 206B/OH-58A) Kiowa helicopters are parked at Bundaberg Airport, presumably to participate in local Anzac Day commemorations.
