Why bother having a clothes dryer when for most of the year you can hang them up in the shade and they will be dry within the hour. There are only a couple of states/regions where it makes sense to use a clothes dryer. The blue mountains and I imagine Tasmania where it gets too cold to hang your clothes up in the winter.
> I would like to see how much energy the average Australian household consumes.
From memory for just myself in a small apartment I used around 9-12 kWh / day. That is rarely using the A/C but having at least one PC running 24/7.
Clothes get dry regardless of the temperature: if it's cold enough, the water will freeze and then the ice sublimates into the lower-humidity atmosphere.
The temperature was only around 23c. In the same temperature in Melbourne, they dry in an hour or two.
