Unleaded 91 and diesel · Brent crude, AUD/USD, capital pump prices, and city-by-city 4-week outlook
What moved this week
As of Thursday 6 November 2025, the national average for Unleaded 91 across Australia's capital cities sits at 186.2c/L, down 4.3c on last week. Diesel averages 188.1c/L nationally, with the cheapest reported bowser at 149.9c/L. Wholesale import costs held steady 0.8% over the past week to an estimated 132.0c/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 2.5% over the past week to US$63.38 per barrel, while the Australian dollar weakened 1.0% 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.
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.

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.
