Help Obtaining acids in Australia?

Can the acids used for CO method be legally or easily purchased in Australia or to Australia? I posted this question in the carbon monoxide mega thread but that place may not answer or be visible enough, sorry.

I just want it to be painlessly be over with minimal effort, sooner or later. Jumping and hanging are far from ideal. I'd drown in the ocean off a cliff without rocks but I'm not wanting to get eaten by marine life before being deceased.
