How many days of fuel does Australia have?

Between the statements for 11 August 2026 and 29 September 2026, petrol went from 41 to 41 days, diesel from 37 to 32 and jet fuel from 35 to 28. The obligation line for each fuel was the same on every statement in the table. A move of one day is the smallest the statement can show, so a flat week is as much a reading as a moving one.

The obligation line in the first table is the Minimum Stockholding Obligation, which requires each fuel importer and refiner to hold a set number of days of its own sales in Australia: on the current statement 27 days for petrol, 32 for diesel and 27 for jet fuel. It applies company by company, so a national figure above the line does not mean every company is above its own, and the days-of-cover figure in the answer is an aggregate of the stock those companies report, read alongside the line rather than against it.

The obligation has been under temporary relief since March 2026: a company that commits to bring more fuel into the domestic market may hold less against its line. The relief was extended to 31 January 2027 (Energy Minister media release, 19 September 2026) and reverts on 1 February 2027, so the line shown is the obligation as written, not the eased holding a company may be running at. The Australian Fuel Security Reserve announced in the PM media release, 12 May 2026 is a different thing again: government-owned stock, to sit alongside the commercial stock the weekly statement counts. This page does not add the two together, and nor does the statement.

Cargoes first: refined fuel arriving by sea joins the stock the week it lands, and the routes it travels and their status are on the fuel supply page. Refinery output second: product finished at the two Australian refineries counts as it is made. The import pool third: the fuel standards settings relaxed in March 2026 (petrol sulphur cap at a transitional 40 ppm until 30 june 2027; diesel minimum flash point held at 60.5 degrees c until 30 june 2027) widen which cargoes can be bought, and both revert on 1 July 2027; how the site reads the reserve figures, and what those settings change, is set out in the supply and policy methodology. Daily use last: it is the divisor, so a quieter week lifts the figure without a litre arriving.

Whether any of this adds up to a shortage is a different question, answered from days of cover, station availability and the supply band together on is there a fuel shortage?This site's own status bar moves to its elevated register when aggregate cover falls to 45 days and to its crisis register at 30; the Commonwealth's scale is the National Fuel Security Plan, at Level 2 of four (Keeping Australia moving) when last checked.

How many days of diesel does Australia have?

32 days on the DCCEEW statement for 29 September 2026, against a 32-day obligation line for diesel importers. The diesel row in the first table carries the stock and the daily use behind that figure.

Who publishes the figure, and how often?

The Department of Climate Change, Energy, the Environment and Water, as the Minimum Stockholding Obligation weekly statistics, published on Saturdays. This site stores each statement and shows the date it covers, not the day it was read.

What would count as low?

This site's status bar moves to its elevated register when aggregate cover falls to 45 days and to its crisis register at 30. The Commonwealth uses a different scale, the National Fuel Security Plan, which sat at Level 2 of four (Keeping Australia moving) when last checked on 6 October 2026.
