The price of petrol I paid during June 2020 averaged $1.19 per litre for 91 Octane unleaded petrol add up to 15 cents more for 95 Octane petrol and usually up to 25 cents for 98 Octane petrol, location is Melbourne Australia. The relatively low prices was maintained throughout the month but I noticed a drop on the last week June to around $1.10 per litre. of unleaded.
The price of diesel was around $1.22 the last time time looked and this the price does not fluctuate much compared to unleaded.
