The average price of petrol I paid during November 2015 averaged $1.20 per litre for 91 Octane unleaded add 10-15 cents for 95 Octane and usually 15-20 cents for 98 Octane. The lowest was during the last week $1.09. The price spiked to $1.33 at the start to the last weekend.
Diesel was priced around the $1.29 per litre the last time I looked.
Note that fuel prices vary according to area and the level of competition and a whole heap of other factors like shopping discounts and so forth.
