Frequently Asked Questions
What is the most common parenting arrangement in Australia?
The most common arrangements are week-on/week-off (50/50) and every-other-weekend with midweek contact. The best arrangement depends on the children's ages, school logistics, parents' work schedules, and the distance between homes.
What is a 5-2-2-5 schedule?
In a 5-2-2-5 arrangement, the child spends 5 nights with Parent 1, then 2 with Parent 2, then 2 with Parent 1, then 5 with Parent 2. It's a 50/50 split with shorter maximum stretches away from each parent compared to week-on/week-off.
How many changeovers is too many?
There's no fixed rule, but frequent changeovers can be unsettling for younger children. Most family consultants suggest minimising mid-week transitions for children under 5. Older children and teenagers generally handle more changeovers without difficulty.
Does the schedule affect child support?
Yes. The number of nights per fortnight determines the care percentage band, which directly affects the child support calculation. A schedule change from 4 to 5 nights could move you into a different band and change the payment amount.
