Hi QFWonabe,
You would have a mixture of on-call days, daily returns and overnights. If you were to do on-call days, you could get anything (naturally). Daily returns can variate from a simple MEL-SYD-MEL to MEL-PER-MEL or something a bit longer like MEL-SYD-BNE-SYD-MEL. The layover destinations are generally the big cities such as MEL, SYD, PER, DRW, BNE, ADL and occasionally but rarely TSV or CNS.
I hope that helps
