A large supermarket chain has the highest gasoline price in the country, at nine points per litre over other retailers.
Gas at the, Coles Express gas stations in Sydney, Melbourne, Perth, Adelaide and Brisbane is the most expensive, according to the (ACCC) report of Australia's Fair Competition and Consumer Council.
In Sydney, ACCC said, prices at the Coles gas station are four cents per litre more expensive than the Woolworths and nine cents per litre higher than the cheapest.
It found that BP was also in the market, where gasoline prices were 3.5 cents per litre more expensive than the average price for all retailers.
Based on 2017 prices, the cheapest chain of gas stations is the Speedway, 5.5 cents / liter cheaper than the median market price.
The report said that if a car owner buys 60 liters of gasoline from Coles every week, he will spend 300 yuan more a year than on Speedway and 125 yuan more than on Woolworths.
ACCC Chairman Sims (Rod Sims) said he was surprised that the difference between the cheapest retailers and the most expensive retailers was so large because they sold almost the same amount of gasoline.
He said the price gap has widened sharply since 2007, when the gap was only 2.3 cents / liter, so it is now more important to decide where to refuel.
"I am surprised that the prices of Coles and BP are much higher than those of Woolworths,7-11 and United and more expensive than independent retailers," Sims said in an interview with the Sunday Telegraph.
These differences are huge, a liter price difference of 9 points.
While some people use comparable app to find cheap gas stations, such as FuelCheck, in government, New York, a recent survey by Australian convenience stores and the Petroleum Marketing Association (ACPMA) found that 90% of drivers always prefer to go to the same or both stations, according to a recent survey by the Australian convenience Store and Petroleum Marketing Association (ACPMA).
Sims hopes that ACCC's findings will prompt consumers to act and change potentially costly habits.
'it 's either cheap gas stations that sell inferior gasoline,'he said.
"you don't really have to worry about filling the gas station with water," he said. "they all buy gasoline from big companies. Their gasoline usually comes from the same tank (the same as the gasoline sold by BP and Coles). "
The main difference, he says, lies in the interior of the store. Coles and BP have bigger, better stores, he says.
"Independent retailers usually don't have a lot of stuff in their stores," Simms said. "you can't buy anything but coke and cigarettes."
A spokesman for Coles responded to the survey: "Coles Express has been committed to providing competitive gasoline to our customers, and our convenience stores offer a range of food, drinks and household goods at the same price as supermarkets. Leading the market in cost-effective terms. In addition to a discount coupon of 4 cents / liter for 30 yuan shopping at the Coles supermarket, consumers can save 10 cents / liter fuel charges by spending more than 20 yuan on the Coles Express. These discounts can be used separately or superimposed, saving customers a total of 14 cents / litre. "
