What is the petrol price forecast for Melbourne this week?

Check the live indicator above — it scores today against the recent Melbourne average and the public reference median to call trough, rising, peak, or falling. That short-term read is more reliable than any fixed weekly prediction, because Melbourne’s cycle length itself varies.

Will petrol prices go up or down this week in Melbourne?

It depends where the cycle sits right now. If the indicator shows trough or falling, the next few days are more likely to hold or ease; if it shows peak or rising, a reset has likely just happened and prices are more likely to climb before they fall again.

How accurate are petrol price forecasts?

Short-term cycle forecasts (this week) are reasonably reliable because they are based on where Melbourne sits in its current discount-and-reset pattern. Medium-term forecasts (this month or longer) are inherently less certain because they depend on global oil supply, refining margins, and the Australian dollar — treat those as directional guidance, not a guaranteed price.

Is now a good time to fill up in Melbourne?

If the live indicator above shows trough or falling, filling now is usually a good call even with a half-full tank. If it shows peak or rising, it is reasonable to stretch the tank a few days if you can — but never wait on empty hoping for a lower price that may not arrive on your timeline.

What is the diesel price forecast for Melbourne?

Diesel does not track the petrol retail cycle closely. It moves more with global distillate supply, freight and mining demand, and refinery output, so a petrol forecast cannot be applied to diesel. Watch global distillate supply commentary and our diesel pricing coverage separately rather than assuming diesel will follow petrol’s next move.

What causes petrol price forecasts to be wrong?

The two timescales can offset each other. A local retail discount phase can mask a rising global oil price, or a falling global price can be hidden by a city deep in its peak phase. Forecasts that only look at one timescale — just the cycle, or just oil prices — miss the other half of the picture.

Petrol price forecast: is Melbourne heading up or down right now?

There is no single number that tells you where petrol prices are going — there is a short-term retail cycle signal that updates daily, and a slower medium-term outlook driven by global oil markets. This page leads with the live signal, backs it with a 4-week history chart, and links to the deeper guides for the medium-term factors.

The cycle indicator needs sufficient recent price submissions to score today's phase. In the meantime, compare live suburb pages to gauge today's market — if many suburbs show prices below 192.7¢/L, the market is likely near a trough.

Rising — past the trough

Average prices have risen 1.2¢/L since the prior window. The cycle is heading toward its peak — fill earlier in the week if you can.

Last 7 days averaged 187.4¢/L for ULP 91 vs 186.1¢/L the week before — based on the public Melbourne snapshot, not a single station.

Four-week Melbourne ULP 91 history

The evidence behind the forecast: daily metro-wide average for unleaded 91 against the reference median. A rising line into today usually means a peak is close; a falling line usually means the trough is close.

What moves the medium-term forecast

The week-to-week cycle is the most reliable short-term signal, but four slower-moving factors set the level the cycle moves around: OPEC+ supply decisions, Asian refining margins, global fuel demand, and the Australian dollar against the US dollar. None of these move on a fixed schedule, and they can offset each other. For the full breakdown of how each factor pushes prices up or down, read when will petrol prices drop.

Diesel price forecast — a different signal

Diesel does not follow the petrol retail cycle. It tracks global distillate supply, freight and mining demand, and refinery output more closely than local retail competition, so a petrol forecast cannot be applied to diesel directly — Melbourne's current board average is 193.5¢/L. Refinery maintenance schedules and industrial demand swings can move diesel up while petrol is falling, or the reverse. See why is diesel so expensive for the supply-side drivers behind that gap.

How to use this forecast

Trough or falling — fill now, even with a half-full tank. This is the most reliable part of any forecast.
Rising or peak — stretch the tank a few days if you can, but never wait on empty hoping for a lower price that may not arrive on your timeline.
Check ULP, premium, and diesel separately — premium often moves first and can hint at the next reset, while diesel follows its own schedule entirely.
Pair this page with a suburb directorypage on your regular route — the city-wide forecast sets the level, but local competition decides today's cheapest bowser.
