Hi I was wondering if anyone has a cheaper way for me to get the extra 80 status credits I need

as follows

akl-mel-syd-cns-bne-mel

cost is about $395 AUD or $473 NZD

works out to about 4.94 a status credit anyone got a cheaper option based in melbourne but can get to anywhere reasonably within Australia or NZ and I dont really need more points so the main thing is dollar cost of status credits
