Petrol prices are on a major spike in these parts at present. There are two fuel stations within 10 km that are under $1.50 per litre, most suburbs/regions are either side of $1.65 & those prices are for 10% ethanol fuel - regular 91-octane is a few cents per litre higher.
In one rural city some 50 km away, most fuel stations are in collusion, it would appear. Their prices are even lower than my local ones, most being around $1.44 per litre - they’ve been keeping their prices lower than surrounding districts for at least 18 months.
