Tasmania, Hobart plants wanted

[Dicko]

Hi all,
Are there any Aussies / Tasmanians here? Theres a few plants/seeds im trying to track down.
- Sceletium tortuosum
- Ephedra sinica
- Sida Cordifolia

- Catha edulis
I realize that one or more of these arent 'available' in Australia, but hey theres gotta be someone out there with a stash ;) 

Sida is a pest in tropic Australia but im in Tasmania so its a bit harder to find or get seeds sent.

Any help appreciated thanks
