maybe not the greatest or most comfortable airline
however my experience has been fine so far
maybe because the Adl-Melb route I use is short.
so travel during Christmas
Adl - Melb $49.95 and visa versa.
I know it has been $39.95 before aswell but I am taking into account the seasonal peak period for which $50 is not bad.
here are some dates, rest see link

Melbourne from $49.95 travel 10 Dec 13 - 25 Oct14
