What is the terminal gate price? A plain-language explainer for fuel and diesel pricing
If crude oil is falling, why is your diesel going up? A plain-language guide to the terminal gate price and what really shapes your bulk fuel costs.

It's a question we hear often, and a fair one: "If the news says crude oil prices are dropping, why is my diesel going up?"
The short answer is that several different prices sit between a barrel of crude oil and the diesel going into your tank, and they don't all move together. Here's a plain-language look at what's actually going on, including how the terminal gate price fits in and what else makes up the final price you pay.
What is the terminal gate price?
The terminal gate price (TGP) is the wholesale price of fuel at a fuel terminal. It's the price published each day for buyers picking up product directly from the terminal, before any retail margin, freight to your property, or local delivery costs are added.
For Liberty Rural customers, the terminal gate price is the underlying wholesale benchmark that sits behind the price of your bulk diesel and petrol. You can see current Liberty Oil terminal gate prices on our terminal gate pricing page
The terminal gate price moves with two main inputs: the international price of refined fuel, and the cost of getting it into Australia. Here's how each piece works.

Crude oil is an input. Diesel is the finished product.
Brent Crude is the global benchmark price for crude oil. It's the raw material that goes into refineries.
Diesel, on the other hand, is a finished product. The benchmark for diesel pricing in our part of the world is the Singapore Mean of Platts (MOPS) price for diesel. That's the reference point for what refined diesel is actually trading at on the market, ready to be shipped.
The two move differently because they measure different things. Brent Crude reflects the cost of the raw input. MOPS reflects what the finished product is worth once it's been refined. Plot the two against each other over time and you'll see them converge in some periods and diverge in others. They're related, but they're not the same thing, and they don't always move in the same direction.
So when you hear that crude is down, it doesn't automatically mean diesel will follow. Sometimes it does. Sometimes it doesn't. Until people accept that the two prices don't always correlate, the question keeps coming up: why is the price of crude going down, but the price of diesel going up?
The answer is that the cost of refining, demand for the finished product, and the cost of moving it can all push diesel in a different direction to crude on any given week.
Then there's the cost of getting it here
There's another piece most people don't see: shipping.
Australia imports around 80 to 90 per cent of its refined fuel, which means much of what arrives at our terminals has been transported by tanker from refineries overseas. The cost of that shipping is tracked through something called Worldscale, an internationally standardised system for calculating tanker freight rates for specific voyages.
Freight is a large contributor to the landed cost of fuel in Australia, and it feeds directly into the terminal gate price. When global shipping rates rise, even if the underlying product price is flat, the cost of getting fuel here goes up. That flows through to what you pay at the pump or on bulk delivery.
So at any given moment, the terminal gate price is a reflection of two moving parts: what refined diesel is worth on the global market, and what it costs to ship it to Australia.
What else makes up the final price
The terminal gate price is one piece of the final cost, but it isn't the whole picture. From the terminal gate forward, you also need to factor in:
- Fuel excise, set by the federal government
- GST
- Freight from the terminal to your property
- Any retail margin if you're filling up at a service station
All of these combine into what you actually pay, whether that's at the bowser or on a bulk delivery to your farm tank. The terminal gate price is the wholesale starting point, not the end price.

Why diesel is especially exposed
Diesel matters more to regional Australia than most people realise. We use more diesel per person than any country with a population above 500,000, and most of it goes into road freight, mining and agriculture. So when global pressure hits diesel supply or shipping costs, it shows up quickly in terminal gate prices and right out where the headers, trucks and pumps are running.
That's why diesel pricing can move sharply even when petrol holds steady, and why the daily terminal gate price is worth keeping an eye on.
How to read the Liberty Oil terminal gate pricing page
Our terminal gate pricing page lists the current wholesale price by terminal location and fuel grade. It's the live wholesale benchmark, updated regularly, so you're seeing current numbers rather than something from days ago.
A few things worth keeping in mind when you're checking it:
- Terminal gate prices vary by location, so look at the terminal closest to your property
- They're for the wholesale grade at the terminal, not the retail price you'd see at a service station
- Day-to-day movements often reflect the international price of refined fuel and shipping costs working their way through

What this means for bulk fuel customers
For bulk delivery customers, the terminal gate price is the wholesale benchmark that sits behind the price of your delivered fuel. On top of that, you've got freight from the terminal to your property and any margin Liberty Rural needs to keep the trucks running and the depots open.
We don't control the inputs that drive TGP movements. None of them sit on a single dial we can turn. What we can do is be straight with you about what's driving the price when you ask.
If you're trying to plan your fuel costs through the season and want to talk through what's happening with terminal gate prices in your area, your local Liberty Rural depot is the place to start. We can give you the context you need to make decisions, and we'd rather have that conversation than leave you guessing.
