Use {{location|AU}} to tag expeditions that took place in Australia. It will add Category:Expeditions in Australia to the expedition.
Using ISO 3166-2 abbreviations, you may also tag the state/territory that the expedition took place in. The abbreviations Queensland, Tasmania and Victoria may be in full caps or have only the first letter capitalised.
You may also tag the local government area (LGA) in those states where the LGAs are mapped on OpenStreetMap. Currently, these states are New South Wales, South Australia, Tasmania and Victoria. The LGAs of the Northern Territory or the states of Western Australia and Queensland have not been mapped on OpenStreetMap. This template uses HASC as abbreviations for the LGAs. In some cases, HASC is outdated and the template had to establish its own codes for some newer LGAs. See the source code of this template for them.
Several territories are not covered by Australia's ISO 3166-2 codes, use their own respective ISO 3166-1 codes for them. They are Christmas Island (CX), the Cocos (Keeling) Islands (CC), Norfolk Island (NF) and the Heard Island and McDonald Islands (HM). The Australian Antarctic Territory is covered by Antarctica's AQ code.
Several territories are not covered by Australia's ISO 3166-2 codes, and also do not have their own ISO 3166-1. To tag expeditions that took place there, use abbreviations established by this template, see the examples section for them.
If the category link appears red, do not worry and create the category. Make sure that it is included in the appropriate parent category, for instance, Category:Expeditions in the City of Melbourne is a subcategory of Category:Expeditions in Victoria which is a subcategory of Category:Expeditions in Australia. The subcategories should be sorted in by their respective code.
