I am a QantasLink Q400 Pilot, I usually do short 1 hour flights from airport to airport up and down the East coast of Australia. My main airports I like to visit are:
Port Macquarie Airport
Gold Coast Airport
Brisbane
Melbourne
Newcastle
Lord Howe Island
Bathurst
Sydney (my main hub)
I also fly for the Royal Australian Air Force using a C-130 Hercules. Richmond, NSW is my main hub for RAAF flying and training.
I visit many more but these are my main airports that I personally like :).
