Other costs and taxes
All fuel prices include GST of 10 per cent of the total price. For petrol and diesel you also pay the fixed Federal Government Excise of 38 cents per litre. LPG currently has a lower rate of excise than petrol and diesel. The excise on LPG is currently 5cpl and will rise by 2.5 cpl each year until it reaches 12.5 cpl in 2015.
For petrol and diesel there is also an additional cost, which reflects the higher quality of Australian fuel standards.
