Massive travel period from 26 Dec 2014 to 24 Oct 2015.
Flights go on sale from 12.01am on Tuesday 28 Oct.
I would expect that the Bali to Melbourne sector would cost less than $99 due to lower taxes.
You can also price beat with Jetstar to save $9 if you want to.
I couldn't see any of this fare , where did you get this from
Cheers
