Right now Tiger fares can be had for $119 each way for SYD-CNS, excluding bags. Just check their website for available dates (e.g. I checked and you could fly to CNS on 10 November or 18 November for this price). $119 looks like some kind of sale fare.
Also check if Jetstar has a flight leaving within an hour of Tiger's flight. If so you can use the Jetstar 10% price beat guarantee and also avoid credit card fees.
