Parenting under the Family Law Act 1975 (Cth) is Commonwealth law and applies uniformly across the country, so the core framework does not change between jurisdictions. Where the states and territories matter is in the surrounding services, the courts you deal with, and the practical mechanics of changeover and safety.
New South Wales parents deal with the largest registry of the Federal Circuit and Family Court of Australia, and Sydney's family dispute resolution services carry significant waitlists, which is worth factoring into your section 60I timing. Where family violence is a concern, a NSW Apprehended Domestic Violence Order made under state law sits alongside the federal parenting framework, and your plan's changeover arrangements should be drafted so they do not put either parent in breach of an existing order.
Victoria operates a well-developed network of Family Relationship Centres and the Victorian Family Violence Intervention Order regime under the Family Violence Protection Act 2008 (Vic). Melbourne parents frequently use supervised or neutral-location changeovers arranged through community contact services, and naming that service in the plan removes a recurring flashpoint. Victoria's cultural diversity also makes the section 60CC focus on cultural needs a live drafting consideration rather than a formality.
Queensland covers vast distances, and relocation between regional centres and the south-east corner is a common source of dispute. A Brisbane or Townsville plan should be explicit about travel arrangements, who bears the cost and logistics of long-distance changeover, and how school-holiday flights are booked. Queensland's Domestic Violence Order framework under the Domestic and Family Violence Protection Act 2012 (Qld) again interacts with changeover clauses and should be checked before finalising.
Western Australia is the outlier every Australian parent should know about. Family law for children of unmarried and de facto parents is governed not by the Commonwealth Act but by the Family Court Act 1997 (WA), administered by the separate Family Court of Western Australia. The concepts are closely aligned and WA adopted parallel best-interests reforms, but the section numbers and the court differ, so a Perth parent should confirm the WA-specific pathway before assuming the federal provisions apply directly.
