Joule.

A real-time gauge for how your trip affects New South Wales' fuel security — so you can keep moving, smartly.

Why it matters today Australia holds just 29 days of diesel cover and 39 days of petrol. Around 20% of the world's seaborne oil passes through the Strait of Hormuz — a waterway that has been disrupted for weeks and whose status remains contested and volatile. Every kilometre you don't drive is a litre that stays in the national reserve for essential services.

Plan your trip

Tell us where you're going. We'll score it against the network.

Pick a mode, corridor, and distance. Joule reads the NSW fuel security index, the state's freight load, and the current trip's impact — then tells you whether your plan helps, holds, or hurts, and suggests one small swap if it would make a real difference.

Choose your first-pick option. We'll show alternatives below.

This trip holds the line.
A solo car commute from Blacktown adds moderate pressure to NSW's fuel reserve, but the corridor has room to absorb it this week.

Joule suggestion
Swap one car commute a week for the T1 train. With Sydney ULP at 213.1 c/L and diesel reserves sitting at 29 days, a single weekly swap returns about 3.2 L of petrol to the reserve each week — roughly 166 L over a year, or about 3 tanks of petrol, saving you about $354 at the pump.

How Joule works A single number, in joules, for every choice you make.

Joule converts your trip into a single score from 0 to 100. A higher score means your choice puts less pressure on the state's fuel reserve — and the transport network has more room to absorb it.

60%Fuel impact + 25%Corridor load + 15%Time cost to you

Your fuel impact is measured in kilowatt-hour-equivalents — so electricity, petrol, and diesel all sit on one axis. Corridor load reads live bus and train capacity on the line you're using: if your train has spare seats, your walk-on trip is worth more to the state. Time cost keeps the score honest — if the alternative takes two hours longer, Joule won't pretend that's a free swap.

Joule never tells you not to travel. The goal is the opposite: keep New South Wales moving, with one fewer barrel of imported fuel behind every journey.
