The Space Activities Act 1998 was enacted by the Australian Government to regulate commercial space activities carried on either from Australia or by Australian nationals outside Australia. The Space Activities Regulations 2001 provide further detail about the requirements of Government space activity authorisations. In general the Guidelines provide explanatory advice on the space licensing regime and its administration to assist those intending to conduct space activities. The Space Activities (Approved Scientific or Educational Organisations) Guidelines 2004 are the exception, being administrative guidelines that form part of the licensing regime.
