Homes in Australia are mostly all electric.

Depends on state. Most space/water heating in Victoria is natural gas.
Queensland/NT use a lot of solar hot water, with minimal requirement for
space heating. Cooling is their obvious demand, which of course is electric,
ignoring passive insulation etc.

That'll make using less energy easy then.

Is there a lot of coal generated electricity and if so is the coal of
local
origin ?

Yes, mostly. Some hydro electricity, and some gas fired electricity. A
miniscule amount of solar and wind electricity, but that is increasing.
No nuclear yet.
