"Is it illegal to pay a pilot under the award wage?"
It is illegal for an employer to pay an employee less than the Award (with or without agreement), where an Award is in force. This is a requirement under the Federal Workplace Relations Act 1996 (or in Queensland, The Industrial Relations Act 1999).
For workers not covered by an Award (i.e. no Union coverage, e.g. certain computer workers, cotton chippers and certain other agricultural workers), the minimum wage in Queensland is $431.40 per 40 hour week.
