People joining the Reserve make a commitment to train and serve in the defence and protection of Australia.

Defence Reservists make a commitment to train and serve in the defence and protection of Australia. The support of their employers and families, as well as the community, is vital. The Australian Defence Force (ADF) is increasingly drawing on the skills and expertise of these part-time military personnel to maintain the ADF’s capability.
Reservists have provided humanitarian relief to communities in Pakistan, Thailand, Rwanda and Somalia. They served alongside their full-time counterparts to increase security and stability in Timor-Leste and Bougainville. They are currently deployed on operations in Afghanistan and the Solomon Islands, and regularly deploy an infantry company group to Malaysia as part of Australia's commitment to the Five Power Defence Arrangement.
Reservists fulfilled important security roles at the APEC Australia 2007 forum, the 2006 Commonwealth Games in Melbourne, the Sydney Olympic and Paralympics Games, the Commonwealth Heads of Government Meeting and the 2003 Rugby World Cup.
Reservists make a valuable contribution to the community, providing assistance in times of natural disasters such as floods, droughts and fires and in emergency rescue operations. More than 1300 Reservists were involved in Operation Victoria Fires Assist in early 2009. Employer support gave Defence Reservists the ability assist their fellow Australians during this tragic bushfire disaster.
