Fortunately we are in the position that we were able to take advantage of the Gillard Government initiative to install solar panels. Since then we have not had to pay a electricity account, in fact we receive a cheque regularly.
Being on Centrelink benefits, I get a card from my electricity retailer to pay $50 a fortnight, thereby avoiding a huge bill later that I can't pay in one go.
Even those without this special card could still pay smaller amounts regularly. I have no gas at my current place so everything here is electric.
