What this means for pump prices
Brent crude held 0.9% over the past week to US$94.32 per barrel, while the Australian dollar weakened 1.6% against the US dollar, lifting 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. Retailers absorbing costs — prices likely to rise Petrol stations are currently selling 15c/L below their typical margin — an unusual situation that historically corrects upward. Prices are likely to rise in the coming weeks regardless of where crude goes. This is a good time to fill up.
Import parity hasn't moved much this week, so any pump price changes you see at the bowser will be driven mainly by the local discounting cycle rather than the global signal.

City-by-city cycle outlook

Perth

Looking ahead
Sydney, Melbourne, Brisbane, Perth, Adelaide, Canberra, Hobart, Darwin are on the falling leg, which is when local prices typically reach their lowest before the cycle resets.
If your tank can wait, the next predicted price low is approaching in Brisbane (around 0 days away from the next trough), Darwin (around 0 days away from the next trough). Conversely, drivers in Perth are at or near the cycle low and the model is calling fill-up now before prices reset upward.
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.
