December is always an interesting time in terms of petrol price trends. Generally speaking, retailers hold off on increasing fuel prices during the last few days prior to Christmas, meaning that prices may either jump next week, or the current pump prices around the country will remain stable well into the holiday period. Sydney will most likely experience stability, while Melbourne and Brisbane markets may enter a high cycle next week.



Current ULP average: 169.4cpl

Price range over the last week: 143.9cpl – 193.9cpl

Brisbane is still 1-2 weeks away from the bottom of their fuel price cycle, however, petrol price trends have definitely shown a drop over the past week.



Current ULP average: 178.2cpl

Price range over the last week: 143.9cpl – 193.9cpl

Retailers have priced ULP in the 180 – 190 range this week, indicating Sydney has reached the peak of their fuel price cycle.



Current ULP average: 160.3cpl

Price range over the last week: 140.0cpl – 194.9cpl

With the considerable drop in fuel price trends over the past 7 days, it is likely that Melbourne will experience another petrol price cycle prior to Christmas.



Current ULP average: 144.3cpl

Price range over the last week: 135.8cpl – 184.9cpl

With the pump price of ULP reaching the 184.9cpl mark at several retailers around the city, this is indicative of the new price cycle for Adelaide. With that in mind, more retailers are likely to follow suit and hike up their fuel prices.



Current ULP average: 164.2cpl

Price range over the last week: 141.8cpl – 193.9cpl

The Perth price cycle has hit the midway point, with the next price drop due on Tuesday the 14th.
