Bushwalk Australia

Anybody know of any On-Line retailer who may still have stock of this versatile adapter; or the Brunton version?
I thought I'd try this before jumping into a dedicated remote canister stove

Even tho I just bought a new FireMaple via Ali-Express I still want one of these remote adapter bases, I just bought a S/H SnowPeak GigaPower stove as a back-up and I simply do not trust the unbranded crap being sold for $6- on the same site
