Questions people ask about this run

How much does fuel cost from Perth to Broome towing a caravan?

About $1,149.78 for a Defender 110 towing a 3.2-tonne off-road caravan, planned against the official prices and the wind forecast on 4 September 2026: 446 L over 2,373 km at roughly 19.3 L/100 km.

How many fuel stops from Perth to Broome?

8 towing and 5 solo on this plan, with an 89 L tank starting a quarter full. The longest run between stops towing is 362 km.

Does the wind matter on Perth-Broome?

On 10 September it saved the caravan run $12.80 (-5.0 L). FuelOracle checks the forecast wind on each leg for the day you leave, so the same road can price differently on a different day.

What would filling up at every servo cost on this run?

$1,255.16 towing. FuelOracle's plan saves $70.49 by choosing where to fill and how much to buy, not by driving further or filling less than it needs.

How the numbers are worked out

Fuel burn is modelled for this rig: the van behind it, the speed it holds, the climbs and the wind on every leg. The model is checked against the rig’s real fill-ups and tuned over time. Old-school is the same driver with no planning: fill to full at every stop, and whenever the next servo is out of reach.

Worked examples only

These plans were generated once, on a fixed date, to show how FuelOracle helps you plan better and save time and money. Prices, opening hours and wind have all changed since, and every price and saving shown is a guide, not a guarantee. Do not use them to plan a real trip: plan your own and FuelOracle will plan it on today's prices and forecast.

Example plans use official state fuel price feeds and Open-Meteo wind forecasts, captured once on 4 September 2026. Coastline from Natural Earth. FuelOracle is an independent app and does not represent a government entity.
