What moved this week
As of Wednesday 8 April 2026, the national average for Unleaded 91 across Australia's capital cities sits at 226.8c/L, down 13.3c on last week. Diesel averages 323.1c/L nationally, with the cheapest reported bowser at 289.9c/L. Wholesale import costs eased 3.5% over the past week to an estimated 159.3c/L — the input that flows through to pump prices over the following one to two weeks.

What this means for pump prices
Brent crude eased 4.0% over the past week to US$96.50 per barrel, while the Australian dollar strengthened 1.9% against the US dollar, trimming the local cost of imported fuel. 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 higher. Prices likely higher over the next 4 weeks The cost of importing petrol is up 5% — crude oil has risen 9% recently. Both factors increase what retailers pay before they set prices at the pump. Even at the next price cycle low, expect to pay more than last month's low. If your tank allows, fill up a little more than usual now.
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.

City-by-city cycle outlook
Where each capital sat in its local discounting cycle on Wednesday 8 April 2026, and what the model was telling drivers to do.
Shared signal — Sydney, Melbourne, Brisbane, Perth, Canberra
Even though the price cycle suggests waiting, import costs have risen 5% in two weeks. The next cycle low will likely be higher than recent lows. Filling up now locks in a better price than waiting.

Sydney, Melbourne, Brisbane, Perth, Canberra are 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 Sydney, Melbourne, Brisbane, Perth, 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 upward 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.
