Sorry I can't help you with any plants but I was chasing up a couple of plants for myself a few weeks to take the pressure of the one I have already butchered. I rang around all the local nurseries and they said that they don't tend to stock them until spring as the young plants tend to get knocked by the cold. Point is if you are able to get your hands on some, it might be worth protecting them a little until we get some warmer weather. Most of the nurseries I rang (Geelong) said they wouldn't get any in until October so I'm assuming Melbourne nurseries would have a simular strategy. I'm not sure how far Kuranga nursery is from you but they have them for $13.95 (though I think that price is a bit steep). Most nurseries I rang sell them for the standard $7-8.
Woo-Hoo!!!! I'm not a bludger anymore
