How this update is generated
Each day at 18:00 AEST, PetrolCast fetches the latest Brent crude spot price and AUD/USD exchange rate. These are combined using the standard Singapore MOPS import parity formula to estimate the current wholesale cost of fuel delivered to Australian terminals.
When the import parity estimate moves significantly — up or down — relative to current retail prices and the 60-day average retail margin, the forecast direction and confidence level for each city are updated automatically.
This is different from how other Australian fuel apps forecast prices. They extrapolate the local price cycle forward based on historical pattern recognition. PetrolCast overlays forward-looking market signals on top of cycle analysis, so you get earlier warning of unusual price movements.
