Australia, like many countries around the world, is in the grip of a fuel crisis.
The nation has experienced some of its biggest ever spikes in petrol and diesel prices - and the lorry industry has been among the hardest hit.
Operators are reliant on diesel, often to power heavy long-haul road trains, and many say costs have more than doubled since war broke out in Iran, sending oil prices to record highs across the globe.
In a rare national address, Australia's prime minister recently made a three-and-a-half minute plea about the country's fuel supplies.
"These are uncertain times," Anthony Albanese said during the prime-time televised address.
