Compared with many other countries, Australia has a relatively high divorce rate, driven by a range of macro-level factors including multicultural integration, differing immigration backgrounds, and the retention of traditional values. By early April 2023, 51,076 couples had divorced; in 2019, 2020, and 2021, the number of divorces was 48,582, 49,510, and 56,244 respectively, showing a year-on-year upward trend (data from the Australian Bureau of Statistics and IBIS World reports). When divorcing in Australia, one of the matters that spouses must consider carefully is the question of child custody. The following discussion will focus on child custody in the context of divorce, walking step by step through what a child custody agreement is, what it should contain, how to put one together, and how the courts approach these matters.
