Here are a few pie charts -

They typically put heating + cooling between 35 and 50% of energy use.
To achieve 50% reduction you would have to either throw away all heating 
and cooling or use much more heating and/or cooling than average.

Central heating is a big number in cold climates, but that's not most of 
Australia.
