How Melbourne's Fuel Cycle Works
Melbourne's petrol prices follow a well-documented 7-day cycle driven by coordinated retail competition. Prices typically hit their lowest point on Tuesday and Wednesday mornings after a controlled reset from the previous weekend's high. This trough is the optimal fill-up window for most Melbourne drivers.
The cycle then begins to rise on Thursday as retailers incrementally lift prices ahead of weekend demand. By Friday afternoon and Saturday morning — peak leisure travel periods — prices are typically 20–30¢/L above the Tuesday trough. Sunday represents either the continuation of peak pricing or the beginning of the next drop, depending on how strongly the cycle reset occurs.
Not all suburbs move identically. Inner-city stations tend to reprice faster and show sharper intraday movements. Outer-growth suburbs can hold their trough longer as new entrants compete for volume. Freeway-adjacent stations often carry a small premium year-round for accessibility convenience.
Practical Fill-Up Strategy
- ✓Best days: Tuesday and Wednesday mornings. Prices are near the weekly trough across most Melbourne suburbs.
- ✓Reserve buffer: Keep at least a quarter tank to avoid filling on Friday or Saturday when prices are highest.
- ✓Long weekends: Fill on Tuesday–Wednesday before the weekend. Pre-holiday demand often pushes Thursday prices above the normal weekly pattern.
- ✓Station selection: Combine cycle timing with suburb comparison. The cheapest day plus the cheapest suburb multiplies your saving.
