Someone can confirm if this is wrong but looks like the flights are now on the TigerAir website
Perth - Bali from $89
Adelaide - Bali from $99
Melbourne - Bali from $129
Saw some much cheaper return flights while looking around, $90 for Melbourne, $47 for Perth
Also when searching the flights i found:
