Energy usage is presented as an average estimate while costs and usage will vary according to things like the size of your home and your personal preferences.
Cost figures are based on an average electricity rate of $0.22 per kilowatt hour (kWh) and a gas rate of $0.0147 per millijoule (mJ) excluding GST. Due to your geographic location, the different number of tariffs and the exclusion of the Service Availability Charge (SAC), results may not be an accurate reflection of your bill and actual costs may vary between households.
Figures for thermostat-controlled appliances have also been averaged to take into account appliances that are normally on continuously and switch themselves on and off to maintain pre-selected temperatures.(T) =Thermostat controlled appliances
