To work as a building practitioner in Western Australia, registration with the Building Services Board is required. If you intend to be the ‘nominated supervisor’ of a building contractor, you must be registered as a building practitioner. Study the Diploma of Building and Construction (CPC50220) in WA with Vortex Education. If you are a builder and you neither intend to seek building permits from local government permit authorities, nor intend to contract directly with others to provide building work valued at over $20,000, you do not need to be registered. When considering an application for registration as a building practitioner, the Board considers, among other factors, the applicant’s qualifications, experience and fitness to be registered.
