Sorry for the lack of traffic here and personally I can't answer your quetions. I'm sub-tropical and both grow here so I can't vouch for hardiness further south.
I WILL (if I can dig them out) see if I can find you some links to people who may be able to help.
While in Sudney at the gardens you should be able to get info on the Wollemi pine, which is now in commercial production |
Here is a link that might be useful: wollemi pine
