Arrived at the airport, and about an hour before the plane was to leave, checked the price of petrol. Yes. The price was 112.9. Locked in the price for the next week. Sure beats the local prices in the mid 130- 140 range.
Never expected I'd be able to take advantage of the different petrol price cycles in Sydney and Melbourne. A very pleasant surprise.
If you're travelling around Melbourne, or even interstate, make sure you check the price of petrol and take advantage of the large discounts that may be available using the 7 Eleven app.
