What matters for building & renovation in Mandurah

  • Asking a WA removalist for a controlled waste tracking form is the wrong question. Regulation 3(5) of the Environmental Protection (Controlled Waste) Regulations 2004 excludes asbestos from the carrier licence and tracking regime, so there is no tracking form and no quantity threshold for asbestos transport in WA.

  • Western Australia moved onto the national work health and safety laws on 31 March 2022, so WA workplaces now follow the same model asbestos register and licensing rules as NSW, Queensland, South Australia, Tasmania, the ACT and the NT.

  • WorkSafe WA requires health monitoring for workers at risk of asbestos exposure, paid for by the business, with checks before the work starts, roughly every two years during it, and a final examination when the work ends.

  • Residential building work in WA valued over $20,000 must be carried out by a registered building contractor, and that builder must take out home indemnity insurance in your name before accepting any payment or starting work. For Class 10 work the threshold is $50,000, and associated work such as a pergola, fence or swimming pool is not covered at all. Check the policy exists before you pay a deposit.
