The Automobile Association (AA) says fuel prices will increase across the board next month.
Spokesperson, Layton Beard, was commenting on mid-month fuel price data from the Central Energy Fund.
He says the latest data shows increases of around 52 and 57 cents a litre for both grades of petrol, while both grades of Diesel will go up by between 22 and 33 cents a litre.
Illuminating paraffin will increase by 38 cents a litre.
Beard says the data is showing that international petroleum products are the main driver behind the expected fuel price increases expected next Wednesday.
