The lowest I’ve heard in here to achieve Platypus (platinum) was $3,000 - involving indirect routings to Noumea or somewhere like that
The lowest likely ever is to be in Points Club (while it only pays roughly 70% of the original JASAs that enabled fantastic SC) you can get to points club for very little extra cost by credit card churning bonus points) but having gotten there relies upon rewards seats being available
My hack did not involve a passport so was to fly ADLxMEL-OOL
THIS delivers 200 SC doubled up 400 per trip was a lot cheaper but today is $2,126 and easy enough to do on a weekend (and I like trams and trains so it’s riding them through to Brisbane) and I walked from the airport to the Gold Coast YHA and stayed in a cheap private room ($80-100 per night) so my overall cost was manageable (Nowadays, once I made LTG After 24 years, from a lot of business funded Y travel, my low taxed superannuation is able to fund future travel )
The Trans Tasmans from the East Coast
Currently Bris - Christchurch J is $1443 160 SC doubles to 320
4 Status Runs = 1280 SC just under $6,000
So if there’s specials then that drops further
The loophole necessary is to make placeholder bookings during the DSC period and change them later when the J sales are on
