What this means for pump prices
Brent crude eased 1.7% over the past week to US$72.15 per barrel, while the Australian dollar held flat 0.5% against the US dollar. These are the two inputs that, together with refining and shipping margins, determine the wholesale cost of fuel landed at Australian terminals.
The four-week outlook is leaning lower. Retail margins elevated — correction likely Petrol stations are earning 11c/L more than their historical average margin. This level of profitability tends to attract competition and compress prices over time — even if crude stays flat. Prices may ease in the coming weeks.
Historically, moves in import parity take about 10-14 days to show up at the bowser. With wholesale decreases this week, you can expect the pressure to filter through to pump prices over the next two weeks — earlier in metros that follow a tight price cycle, later in regional markets where retailers smooth changes out.

Looking ahead
Melbourne, Brisbane, Darwin are in the rising leg of the local price cycle, so expect bowser prices to climb before they fall again.
Across our coverage, the cycle call leans toward fill-up now in Perth, Adelaide, Canberra — the model's read is that prices are at or near the local trough and likely to climb in coming days.
Layered over the local cycle, the macro signal is biased downward for the next four weeks based on the wholesale cost trajectory. That doesn't always change the day-to-day call, but it does shift where each city's cycle is likely to land relative to recent history.
How this update is generated
Each day at 6:00am AEST, PetrolPulse fetches the latest Brent crude spot price and AUD/USD exchange rate, then combines them using the standard Singapore MOPS import parity formula to estimate the wholesale cost of fuel delivered to Australian terminals.
Capital city averages are computed from live station-level data within a metro radius of each capital — not state-wide aggregates — so regional outliers don't skew the headline number. Comparisons against 7 and 30 days prior show whether the city was trending up or down on the day, separate from the wholesale signal.
The city-by-city cycle outlook combines local cycle-position analysis with the forward-looking macro signals above. When import parity moves significantly relative to current retail prices and the recent margin, the directional call updates automatically.
