Unleaded 91 and diesel · Brent crude, AUD/USD, capital pump prices, and city-by-city 4-week outlook
Produced automatically from PetrolPulse's live pricing data and forecast model — how our forecasts work. Methodology by Mark Schreuder · Data as of 11 July 2026
What moved this week
As of Saturday 11 July 2026, the national average for Unleaded 91 across Australia's capital cities sits at 170.6c/L, up 1.2c on last week. Diesel averages 191.8c/L nationally, with the cheapest reported bowser at 164.3c/L. Wholesale import costs lifted 2.7% over the past week to an estimated 140.3c/L — the input that flows through to pump prices over the following one to two weeks.

What this means for pump prices
Brent crude climbed 5.4% over the past week to US$76.01 per barrel, while the Australian dollar held flat 0.2% 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 8c/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 increases 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.

City-by-city cycle outlook
Where each capital sat in its local discounting cycle on Saturday 11 July 2026, and what the model was telling drivers to do.
Sydney
Cycle position unclearFill when you need toPrices are stable right now. Fri–Sat tends to be the cheapest day in Sydney. Fill up when convenient.
Melbourne

Brisbane
Cycle position unclearFill up nowFri–Sun is historically one of the cheapest days to fill up in Brisbane (up to 4.2¢/L cheaper than the most expensive day). Today is a good day to fill up.
Perth
Cycle position unclearFill when you need toPrices here usually follow a weekly pattern, but there isn't a clearly cheaper day worth waiting for right now — fill up when you need to.
Adelaide
Near peak — likely to fall soonFill up nowFri–Sun is historically one of the cheapest days to fill up in Adelaide (up to 4.7¢/L cheaper than the most expensive day). Today is a good day to fill up.
Canberra
Cycle position unclearFill up nowFri–Sun is historically one of the cheapest days to fill up in Canberra (up to 3.9¢/L cheaper than the most expensive day). Today is a good day to fill up.
Hobart

Darwin
Near trough — cycle lowFill when you need toPrices are stable right now. Saturday tends to be the cheapest day in Darwin. Fill up when convenient.
Looking ahead
Adelaide is in the rising leg of the local price cycle, so expect bowser prices to climb before they fall again; Darwin is on the falling leg, which is when local prices typically reach their lowest before the cycle resets.
Across our coverage, the cycle call leans toward fill-up now in Brisbane, Adelaide, Canberra, Hobart — 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.
