Good economic news is easy to write. Declining industries in Australia rarely get the same column space. That's a problem, because contraction is just as informative as growth, and often more useful when you're trying to understand where an economy is actually heading.

Understanding declining industries in Australia, and specifically why contraction is happening, matters as much as knowing which sectors are growing. Some of these falls are cyclical. Others are structural. Knowing the difference shapes every decision that follows, from investment to workforce planning to policy. Here is what the data says.

Nickel's Collapse: The Battery Dream That Arrived Too Late

The nickel story is one of the starkest examples of declining industries in Australia in recent memory. Revenue in the nickel ore mining sector fell at a compound annual rate of 15.2% over the past five years, dropping to an estimated $1.4 billion. That is not a slow fade. That is an industry losing roughly a sixth of its value every single year.

Indonesian oversupply flooded the global nickel market from 2022 onward. Australian production became structurally uncompetitive almost overnight. BHP curtailed its Nickel West operations in December 2024. Wyloo and Panoramic Resources had already ceased or suspended operations before that. Nickel export earnings, which reached $2.3 billion in 2024-25, are forecast to fall to $1.4 billion in 2025-26 and $1.2 billion in 2026-27, according to the Department of Industry, Science and Resources quarterly data.

Nobody disputes that nickel will matter again when battery markets tighten and Indonesian supply quotas tighten. But 'will matter again' is cold comfort for workers on the wrong side of that timing.

Coal and LNG: The Long Goodbye Gets Louder Every Year

Coal sits at the heart of declining industries in Australia, and it comes with political discomfort that most reports tiptoe around. Twenty-four coal mines are slated for closure before 2030. Thermal coal export earnings are forecast to fall from $32 billion in 2024-25 to $27 billion by 2026-27. Metallurgical coal earnings are similarly retreating, dropping from $39 billion to around $36-37 billion over the same period, per government resources data.

LNG tells a comparable story. Export earnings are forecast to fall from $65 billion in 2024-25 to $47 billion by 2026-27, as lower oil prices flow through to long-term gas contracts and US and Qatari supply floods the market. These are not short-term price dips. They reflect a structural unwinding of the commodity revenue peak that ran from 2021 to 2023.

Iron ore rounds out the picture of declining industries in Australia at the export earnings level. Earnings are forecast to fall from $116 billion in 2024-25 to $107 billion by 2026-27, even as Australia holds its position as the world's largest iron ore supplier. Weaker Chinese steel demand and easing prices are driving the fall.

Traditional Manufacturing: Still Present, Still Losing Ground

Manufacturing in Australia is not dead. It is, however, far smaller than it used to be. The closure of BP's Kwinana refinery and ExxonMobil's Altona refinery in recent years stripped the country back to minimal domestic refining capacity. Manufacturing earnings declined $3.6 billion in 2023-24, per ABS data. Labour productivity fell in eleven of Australia's nineteen tracked industries in 2024-25, with manufacturing among the hardest hit.

The Australian Industry Group's analysis of ABS productivity data groups manufacturing into what they call the six industries where productivity has gone backward since the pandemic, in some cases by a wide margin. Competing with lower-cost offshore producers while absorbing rising Australian wages and energy costs is a difficult equation that has not improved.

Among declining industries in Australia, traditional manufacturing faces the hardest structural challenge: it is losing ground on both revenue and productivity simultaneously, making recovery harder to sustain even when conditions temporarily improve.

Retail and Print Media: Death by a Thousand Clicks

Retail and print media represent a different category of declining industries in Australia. Their contraction is not driven by commodity prices or global oversupply. It is driven by the permanent shift in how Australians spend time and money, and those shifts do not reverse.

ABS data shows retail trade was one of only two industries to record a net decline in the number of businesses operating in 2024-25. Per capita alcohol consumption has been falling for years. Physical newspaper circulation has been declining for over a decade. Foot traffic in traditional retail formats has not recovered to pre-digital norms.

The mechanism here is different from nickel or coal. It is quieter, spread across thousands of small businesses, and largely invisible in the national headlines. But the direction is the same.
