Try this link below. If you cannot connect, use "Australian Plant Society"
in your search.On the general site there is all sorts of info on suitability
of plants to areas and the link to nurseries gives them state by state and
also you could follow the links to the WA group of APS which has more info
again. You can also ask in the Yahoo group "Australian plants". You are
truly fortunate to live in WA as they have the most spectacular plants out
of all the states
