The only professional Australian-made porn in recent years that I can recall was äbout five years ago with "Buffy Down Under" starring Krysti Myst. A semi-pro company called Red Rock also made some stuff with Shayla Laveaux doing some lesbo scenes in the bush.
The short-lived golden age of Oz porn was when a whole lot of US actors (John Dough, Randy Spears and Randy West) came down in the early 1990s and made about a dozen films in Canberra and Mollymook produced by John T. Bone which involved shagging all-natural Aussie sheilas (Sunny MacKay, Alice Springs, Deirdre Holland and a couple of Aboriginal girls). Some of these movies are still available from various online stores in Oz – I recently picked up a good double disc of "Dial-a-Sailor" and "Singles Holiday" (featuring Randy Spears rogering Sunny Mackay on horseback! – something I have only seen done once since and that was last month in a JAV title starring a professional equestrienne!).
There is also a mysterious (because I have never seen it sold anywhere) Australian made porno called Ärigato Baby" from the late 1980s that starred Aboriginal actress Nikki Lane and an anonymous female Japanese student.
