BOCA has 46 branches and affiliates in the southern and eastern states of Australia. In addition to the regional-based branches we have one Special Interest Group - PhotoBOCA - that caters for birding photographers. Whilst the list groups the branches by state, some branches such as Echuca, Sunraysia and Ovens-Murray are close to state borders and cater for members in both states.
Whilst BOCA members are welcome at all branch and affiliate meetings and outings, some branches may charge a small annual fee for their newsletter, and some affiliate groups may also have a membership fee.
