Stupid repressed government here won't allow importation of it, even after the WHO gave it the thumbs up, yet it is legal to possess? What the fuck?

Does anyone know where to get some around Melbourne area, or even some viable work-around?

Sounds like the government there in Australia could use a bit of, good old, hippie activism....
if that fails, fuck some shit up

the answer to your question is: ebay....

Go somewhere that you can buy it, take it back.

Or, as above said, ebay.
