The Association also supports the Australian Naturalists Network.
SEANA usually meets twice a year with the meeting (or campout) held in a town, at a conference centre or in an area with camping facilities. These meetings are organised by one of the member clubs.
The campouts usually have a program of events over two or more days. Events may include outings and excursions, visits to places of natural history interest and lectures and demonstrations. The meeting may also include a biological survey of an area of interest.
The formal meetings of the Association are also held during the program of events. Each Club is entitled to appoint one delegate for the meetings. Many other naturalists from the member clubs, or lone members, attend the campouts and the meetings.
The Association is administered by a Committee of Management made up of nine members. Three members of the committee are elected at each annual meeting, and hold office for three years.
