Help! Extreme electricity bill!

Needs some help on reducing my bills! I've just got my electricity bill for rhe kast month or two, and it's $900, for a single parent family of 3.

I don't think we use that much - I cook w electricity but not even every day (leftovers), we don't use our air conditioner or other heaters.. I've limited rhe kids to a hot shower every 3 days to save there a bit; it's QLD they can have a cold shower.

The meter read is an actual read.

I contacted them to make sure concession was applied and they reissued the bill but it hardly changed.

Any advice please? I can't afford this!
