Yes, I am in Au, and our flora (and fauna) are unique.
None of our standard stuff is deciduous. 
Deciduous stuff from other realms has been planted here.
So I expect that all eucalypts are evergreen.
Casuarina aren't coniferous as they are actually flowering plants, in which 
the flower *resembles* a brown cone.

the broad categories in the UNEP-WCMC system make sense but the terms don't 
cover "Mallee" and the most common type of surviving Australian forest "dry 
sclerophyll" is a term very few mappers would be familiar with.

This is a listing of Australian forest types
from the legend of a map 
http://www.australianforests.org.au/pdf/forest_type.pdf

Acacia
Callitris
Casuarina
Eucalypt Mallee
Eucalypt woodland
Eucalypt open
Eucalypt closed
Mangrove
Melaleuca
Rainforest
Other
Plantation

descriptive work
http://www.australianforests.org.au/australiasforests/forest-types.htm and 
http://www.daff.gov.au/brs/publications/series/forest-profiles

And I had to look up callitris, to find out that is a mere 20km to a large 
callitris forest from home.

The end result of my quick check is that 
1. European or northern hemisphere categories of forest are incompatible with 
Australian flora.
2. Standardised category names may be meaningless to mappers who aren't going 
to use them if they don't understand them.
