Why Unleaded in Ballarat Just Dropped 37 Cents While Dandenong Climbed 12 and What the Price Cycle Tells Us

Here is a question I get asked constantly: how can two suburbs in the same state have petrol prices moving in completely opposite directions at the same time? Right now in Victoria, unleaded in Ballarat has dropped a substantial 36.9 cents per litre while Dandenong has climbed 12.2 cents. Same fuel, same state, same week. Let me explain why this happens and what it means for your next fill up.

The Price Cycle, Explained Simply

Think of it this way. Fuel pricing in Australian cities follows a pattern economists call an asymmetric price cycle. Prices rise quickly over a few days, then fall gradually over a week or two. The key factor here is that not every suburb enters the cycle at the same time. Some areas reset their prices early while others are still riding the tail end of a previous drop.

That is exactly what we are seeing across Melbourne and regional Victoria right now. Suburbs in the falling phase of the cycle are offering genuine savings, while those entering the rising phase are catching motorists off guard.

Where Prices Are Falling

Ballarat leads the charge with unleaded dropping 36.9 cents to around 243.7 cents per litre. That is a meaningful saving. For a 50 litre tank, you are looking at roughly $18.45 less than what you would have paid just days ago.

Bayswater in Melbourne's outer east is also well into the downswing, with unleaded falling 15.2 cents to 245.7 cents. And the good news extends to E10 as well. Frankston E10 has come down 11.1 cents to 226.8 cents, while Hamilton in western Victoria has seen E10 drop 18 cents to just 221.9 cents per litre.

If you are in Reservoir, premium 95 has eased 11.6 cents to 253.3 cents. Even diesel shoppers are finding relief there, with prices down 13.4 cents to an average of 276.5 cents.

Where Prices Are Climbing

The reason behind the simultaneous increases in other suburbs comes down to timing within the cycle. Dandenong unleaded has risen 12.2 cents to 250.6 cents as local servos reset their boards. Lilydale has climbed 11.5 cents to 241.3 cents, and Clayton premium 95 is up 10.9 cents to 259.8 cents.

You might be wondering why servos in one suburb raise prices while the one down the road keeps discounting. Essentially, it comes down to competitive dynamics. Larger chains tend to lead the price reset in specific zones, and independent operators follow within days. The suburbs that reset first are already climbing while nearby areas are still competing on the way down.

the diesel Picture

Diesel tells a different story across the state. Victoria's average sits at 289.1 cents, which is actually the lowest state average in the country right now. The spread is notable though. You can find diesel as low as 189.9 cents in regional areas like Horsham and Timboon, while metro servos push closer to 295 cents. That is a 150 cent spread across the state.

For context, South Australia has the tightest diesel spread at just 12.2 cents between its cheapest and most expensive servos. Victoria's 150 cent gap tells you there are real savings available if you know where to look.

What This Means for Your Wallet

Understanding these patterns helps you predict where prices are heading next and plan accordingly. Here is the practical takeaway.

If you are near Ballarat, Bayswater, or Frankston, fill up now. These suburbs are at or near the bottom of their cycle and prices will start climbing again within days.

If you are in Dandenong or Lilydale, hold off if you can. These areas have just reset and will take a week or so to cycle back down. A short drive to a suburb still in the falling phase could save you $10 to $15 per tank.

The same logic applies to E10. At 221.9 cents in Hamilton, E10 is offering genuine value compared to standard unleaded in most metro suburbs. For cars that can run it, the economics are straightforward.

Let's break this down step by step. Check your local suburb price on our interactive fuel map. If it has recently jumped, nearby suburbs may still be low. The cycle typically takes 10 to 14 days to complete, so the savings window is real but it does not last forever.

Keep an eye on Victoria prices over the coming week. The suburbs currently at their lows will start climbing, and the ones that just reset will begin their gradual descent. That is the cycle at work, and once you see the pattern, you will never overpay at the bowser again.
