The jump came straight after the 2022 east coast flood, the costliest flood in Australian history. Even after it eased, insurance has kept rising faster than prices in general.

Why are insurance premiums rising?

The Reserve Bank put it plainly in 2023: prices rose “reflecting higher insurance premiums due to increased claims arising from natural disasters”.

The Insurance Council of Australia lists four drivers of insurers’ costs: natural disasters, the increasing value of insured assets, inflation in building and vehicle repair costs, and the rising cost of doing business. The last two hit equipment owners directly: repairs to modern machines cost more, and machines themselves are worth more.

How much do natural disasters cost insurers?

  • Since 2019 the Insurance Council has declared 29 extreme weather events, totalling $20.7 billion from more than 760,720 home and building claims.
  • Flood losses alone have increased from an average of $129 million a year in the 2000s to around $2 billion a year since 2020.
  • In 2025-26, insurers responded to seven declared weather events and two non-weather events, which together generated more than 147,500 claims and $3.98 billion in insured losses, up from three events and about $2.2 billion the year before.
  • The February to March 2022 east coast flood was the costliest flood in Australian history.

What will natural disasters cost Australia by 2060?

Natural disasters cost Australia an estimated $38 billion in 2020. Even under a low emissions scenario, that’s forecast to reach $73 billion a year by 2060, and $94 billion a year under a high emissions scenario. The pressure on premiums isn’t going away.

Does this apply to business equipment insurance?

The ABS figures measure insurance bought by households, such as home, contents and car insurance. They don’t measure business equipment insurance separately. But the cost drivers the Insurance Council lists, disasters, asset values and repair costs, are the same ones that sit behind equipment premiums.

APRA’s figures for business lines show 2025-26 was a mixed year, not a uniform rise:

Premiums written (APRA)2024-252025-26Change
Commercial motor$4.94b$5.12b+3.6%
Commercial property (fire and ISR)$9.41b$9.00b−4.4%
Public and product liability$3.94b$3.83b−2.8%
Householders$16.47b$17.56b+6.6%

These are total premiums written by Australian insurers, so they move with the number of policies as well as with prices. They show where the market is heading, not what any one business pays. The point stands either way: on an annual policy, you find out at every renewal. On a fixed multi-year policy, you don’t have to.

What does a fixed premium change?

An annual policy is re-rated at every renewal, so each of these pressures can show up in your premium every year. A fixed multi-year policy sets the premium on day one for up to five years, and it isn’t affected by claims, inflation or market movements during that term.

A fixed premium isn’t a forecast that annual premiums will keep rising. It gives you a known insurance cost for the life of your finance. Multi-year vs annual cover compared.
