You might contact the wholesalers and ask if they supply to a Canberra nursery or a mail order one anywhere.

The current About the Garden Magazine seems to make mention of this plant but I didn't read it (computer running as slow as). If they are worth their salt, they should know where to get it.

If you find it, do tell. It's a very attractive plant.

After sending out a lot of emails to wholesale nurseries I finally found a very helpful person at plantsgalore.com.au (in Victoria) who had some in stock but could only supply to local retail nurseries... again after contacting a number of local Canberra nurseries, who honestly weren't very helpful (one nursery owner actually told me they wouldn't do well in our climate and winter frost would kill them), finally the lovely people at 'Yarralumla Nursery' got them in (after months on their waiting list, I'd given up) even the guy who delivered them to me was impressed by the plants. And I'm proud to say they are thriving beautifully and continued to look great even through last year's frosty winter.

I'll have to track some down for myself. I don't live far from Canberra so enjoy the same delightful (?) winters.
