This is the week where we generally see massive petrol price increases – it will just be a matter of which cities, when, and how quickly prices will peak. Judging by Adelaide’s fuel price trends, it is most likely prices around the country will range from the mid to high 180’s. After the majority of retailers heavily discounted pump prices during the previous week, keep an eye on Brisbane and Melbourne markets in particular this coming week as they enter their new price cycles.



Current ULP average: 157.3cpl

Price range over the last week: 139.9cpl – 193.7cpl

The massive drop in unleaded petrol (ULP) prices this week indicates that it is very likely Brisbane is about to enter a new fuel price cycle.



Current ULP average: 173.5cpl

Price range over the last week: 145.7cpl – 193.9cpl

There was an overall slow downward movement in fuel price trends this week. Unfortunately for Sydney motorists, petrol prices are most likely looking to stay high during the Christmas period.



Current ULP average: 150.0cpl

Price range over the last week: 132.9cpl – 185.5cpl

On average, retailers dropped average fuel prices by at least 10cpl across Melbourne this week – a handy time for motorists to fill up just before the next fuel price cycle, which is due before Christmas.



Current ULP average: 152.3cpl

Price range over the last week: 129.9cpl – 188.9cpl

While average fuel prices dropped over the past week allowing motorists to fill up at very low pump prices, ULP prices significantly increased over the past day, crowning Adelaide as the highest priced capital city this week. Average fuel prices are looking to remain around the 180cpl mark.



Current ULP average: 144.3cpl

Price range over the last week: 138.9cpl – 175.9cpl

With the bottom of the 2-week price cycle having come and gone on Tuesday, today’s new price increase is expected to range in the mid to high 180’s.



Current ULP average: 168.3cpl

Price range over the last week: 131.9cpl – 169.9cpl

Another very small increase in fuel prices for Darwin this week.



Current ULP average: 177.9cpl
