From the Australia Council's website:
Payment of artists
The Australia Council aims to ensure that artists employed as a result of a grant receive pay and conditions appropriate for their work and professional skills. Pay scales and conditions may be prescribed by legally binding industrial awards and agreements, such as those monitored by the Media, Entertainment and Arts Alliance (MEAA). In other cases, arts industry organisations such as the Australian Writers’ Guild, the Australian Society of Authors and the National Association for the Visual Arts have recommended appropriate industry standards. Where an industry standard clearly applies, applicants are expected to meet those rates of pay.
