Hi Ross,
Not certain if they are completely gone from Ngarkat. I think there is a lot of 
active management to protect the few small populations that are left (mainly in 
areas that have escaped the fires). The other mystery is the apparent paucity 
of records from Murray Sunset which would appear to have suitable habitat but 
very low densities (compared to Hattah-Kulkyne).
However, I agree with your sentiment about the fires at Hattah (which have had 
some fires but thankfully not in the highest densities).
Fire is a part of the landscape, but when the landscape has been fragmented and 
isolated through other activities protecting the areas that are left becomes 
vitally important.
