Really? My understanding is that any cuttings or live plant material get you in big trouble in WA, and theres a chance of inspection fee of $56 for a bit of seed, unless it manages to get through undetected. Thanks for the advice
Oh damn, I'm a bit of a cacti noob for identification. I was really hoping it was a peruvianus, since I have none of those and I haven't seen any in WA at the markets or on gumtree. Still a beautiful cacti. Oh well, the hunt continues!
