How the NT and Queensland Work Out Your Farm Insurance Premium
A look at how workers compensation premiums are calculated for farm employers in the Northern Territory and Queensland, and what you can do to help keep your rate down.
If you employ staff on your farm, your workers compensation premium is not just a bill that arrives once a year. It is worked out from your own numbers: your wages, your industry, and your claims history. Knowing how the sum is done makes it a lot easier to see where you actually have some control. This time we are looking at two states that have not had much airtime in this series so far, the Northern Territory and Queensland.
Northern Territory: Industry, Wages and Your Claims History
NT WorkSafe's guidance explains that an employer's premium is based on a rate charged for every $100 of wages, and that rate is shaped by your industry type, your payroll and worker numbers, and your claims history. If your business has had frequent claims, or a few costly ones, you may be charged more than the insurer's standard book rate. On the flip side, a solid safety record and a clean claims history can work in your favour.
Premiums start as an estimate based on your expected wages for the year, then get topped up or credited once your actual wages are known, so keeping accurate, up to date wage records really does matter, both for your premium and to avoid a surprise bill at renewal. Worth flagging: NT WorkSafe's public guidance does not spell out detailed record keeping requirements, and does not give farm specific guidance, so we would treat this as general information and check directly with NT WorkSafe or your insurer for anything specific to agricultural work.
Queensland: Wages, Industry Classification and a Multi Year Claims Look Back
WorkCover Queensland builds a premium from three main ingredients: your declared wages, your WorkCover Industry Classification (which reflects your main business activity and its typical injury risk), and your claims history. For smaller farm businesses, generally those with annual wages of $1.5 million or less, only the claims costs from the most recent financial year affect your rating, and the first $500 of claims cost in a year is protected, so a single minor claim should not move your premium.
Larger operations move into what WorkCover Queensland calls experience based rating, which looks across four years of claims costs (three years of statutory claims plus the most recent year of common law claims) to set the rate. In June 2026, the WorkCover Queensland board held the average premium rate steady for a second year running, at $1.343 per $100 of wages for the 2026 to 2027 year, with the board chair pointing to a balance between supporting businesses and keeping the scheme financially sound.
In both states, the practical advice is the same: declare your wages accurately and on time, keep records of any safety improvements or return to work support you provide, and treat your claims history as something you can actively manage, not just something that happens to you.
