As an apprentices or trainee, you are paid to attend work and training by your employer. Your wage is determined by the industrial award for your industry and agreement set out in your training contract.
An industrial award is the minimum standard that an employer in your industry is allowed to pay for your kind of work. It's a legal ruling which grants all employees in one industry the same conditions of employment and wages.
In many cases, employers are required to pay for or reimburse you for the cost of training fees and textbooks required for the apprenticeship, as long as you make satisfactory progress. In some cases, the award or industrial agreement does not state whether the apprentice or employer is responsible for these costs, so this needs to be discussed between you.
You or your employer may be eligible to receive allowances for costs such as travel, accommodation, or equipment.
