In Australia, commission rates vary between agencies and can range from 10% to 20% of a model's earnings. The commission charged can impact a model's earnings, as it reduces the amount of money they receive for their work. As an example, if a model earns $1,000 for a job and their agency charges a commission rate of 20%, they will receive $800 and the agency will keep $200. Similarly, if a model earns $5,000 for a job and their agency charges a commission rate of 15%, the model will receive $4,250 and the agency will keep $750.
