According to data from the Australian Institute of Petroleum, the national average price of unleaded petrol rose by 5.7 cents last week to six-week highs of 131.8 cents a litre.
 
Falling pump prices: The average price of unleaded petrol has fallen to 13-month lows in Canberra and Hobart and 15-month lows in Darwin according to Motor Mouth.
 
What does it all mean?
 
Aussie motorists have enjoyed lower petrol prices for most of the summer holidays. But discounting cycles have now ended in southern and eastern capital cities. Average unleaded petrol prices are now closer to $1.30 a litre, up by around 10 cents from recent 16-month lows seen in mid-January. Crude oil prices have lifted by 12-15 per cent so far in January as OPEC and its allies have curbed output.
 
Smaller capital cities, such as Canberra, Darwin and Hobart don’t benefit from regular discounting cycles. The less competitive fuel markets have seen unleaded pump prices remain stuck at around $1.50-$1.60 a litre for most of 2018. However, there is some good news for motorists at last. Pump prices in all three cities have fallen over the past week. In fact, unleaded petrol is the cheapest in 13 months in Hobart and Canberra at $1.43 a litre and at 15-month lows of $1.28 a litre in the Top End.
