HF is used all over Australia. Not every airport has VHF coverage (a very very small percentage do), so therefore the use of HF is required.
If you get a chance to listen to some HF frequencies, try one's like 3452, 6610, 8831, 8843, 6541 and you'll hear a wide range of aircraft, from QLink to the Flying Doctors, to all manner of GA aircraft. Mainly for cancelling SARWatch/Times and giving taxi calls, however can be used for anything.
I would use HF almost on a daily basis just flying around Queensland.
