Mine is the Stone Glacier R3 3300 with an xcurve Frame.
I think the closest dealer is in NZ but the price is no better. I bought mine when the Us dollar was near parity so I think all in it was about 800 Aussie.
@Lightweight has a kifaru which is good gear too and there is now a bloke distributing them in Australia. Zac also has a tatonka tent which I've slept in and looks like high quality gear, so I'm sure the packs are the same. Rogee.productions from NZ on YouTube has the tatonka packs and rates them highly.
If I were you I'd try to try a few on if you can, you're welcome to try mine next time I see ya, I reckon with your build and snakehips you will have to do a bit of fine tuning to get the belt to do it's job.
I did see a moroka pack on Facebook for 400 the other day if that tickles you
