All employers must have workers' compensation insurance.
The Workers' Compensation and Rehabilitation and Other Legislation Amendment Act 2003 requires all Queensland businesses which employ workers to hold and maintain an accident insurance policy to cover their workers. A business must take out an accident insurance policy within 5 business days after employing people in Queensland. If you do not take out a policy within this time frame, penalties may apply.
If one of your workers has a work-related injury, workers' compensation will cover their medical costs and lost wages.
As an employer, workers' compensation will cover you for these costs too, as well as costs from possible common law claims.
