Child Support Care Levels in Australia: How Overnight Stays Affect Payments
Child Support Care Levels in Australia: How Overnights Change Your Payments
Child support in Australia isn't a flat number — it's directly tied to how many nights each parent has the child. Every extra overnight you gain (or lose) can shift your care percentage, which changes your cost percentage, which changes the dollar amount of support paid.
Understanding this table is essential because it's the financial framework sitting behind every parenting schedule negotiation.
How the System Works
Child support is administered federally by Services Australia using an income-shares formula. The formula calculates the total cost of raising the children based on the combined gross taxable incomes of both parents, minus a self-support allowance.
Each parent's financial obligation depends on two things:
- Income percentage — their share of the combined parental income
- Cost percentage — the share of child-raising costs they're deemed to meet directly by providing care
The gap between income percentage and cost percentage determines who pays child support, and how much.
The Care Level Table
This is the core reference. Care levels are assessed over a 12-month period.
| Care Level | Annual Overnights | Fortnightly Nights | Care % | Cost % |
|---|---|---|---|---|
| Below Regular | 0-51 | 0-1 | 0-13% | 0% |
| Regular Care | 52-127 | 2-4 | 14-34% | 24% (flat) |
| Shared Care (Low) | 128-175 | 5-6 | 35-47% | 25-49% (scaled) |
| Shared Care (Equal) | 176-189 | 7 | 48-52% | 50% |
| Shared Care (High) | 190-237 | 8-9 | 53-65% | 51-75% (scaled) |
| Primary Care | 238-313 | 10-12 | 66-86% | 76% (flat) |
| Above Primary | 314-365 | 13-14 | 87-100% | 100% |
What the Thresholds Mean in Practice
The 52-Night Cliff
The biggest single jump is at 52 overnights per year (roughly one night per week). Below 52 nights, a parent's cost percentage is 0% — they receive no credit for providing care, and the other parent is allocated 100% of the cost percentage.
At 52 nights, the cost percentage jumps to 24%. This is a flat allocation — whether you have 52 nights or 127 nights, you get the same 24% credit. That cliff creates a strong financial incentive to ensure your parenting schedule crosses the 52-night threshold.
The Shared Care Band (128+ Nights)
Once you cross 128 overnights (roughly 5 nights per fortnight), you enter shared care. The cost percentage now scales incrementally — each additional percentage point of care adds roughly 2% to your cost allocation.
At 176-189 nights (equal time — 7 nights per fortnight), the cost percentage hits 50%. At this point, child support is only payable if there's an income disparity between the parents. If both parents earn the same, neither pays.
The Practical Impact on Parenting Schedules
This financial structure is why parenting schedule negotiations so often circle around specific overnight counts:
- Every-other-weekend only (roughly 52 nights/year) — just barely into the 24% cost credit zone
- Every-other-weekend plus one midweek night (roughly 104 nights/year) — still in the 24% flat zone, no additional financial benefit
- 5 nights per fortnight (130 nights/year) — crosses into shared care, cost percentage starts scaling
- 7 nights per fortnight (182 nights/year) — equal care, equal cost percentage
Courts are aware that financial considerations drive schedule proposals. If a parent is transparently seeking extra overnights to reduce their child support obligation rather than to spend quality time with their child, the court is unlikely to view the application favourably under the best interests framework.

Change of Assessment
If the standard administrative assessment produces an unfair result — because a parent's tax return doesn't reflect their actual financial resources — either parent can apply to Services Australia for a Change of Assessment (COA). Common grounds include:
Reason 8A (Hidden income/assets): A self-employed parent drawing a low wage while their business covers personal expenses, or a parent with substantial wealth in family trusts.
Reason 8B (Reduced earning capacity): A parent who voluntarily reduces their income — quitting a well-paid job, going part-time without a legitimate reason — can have a higher income imputed for child support purposes.
COA applications are free. A Senior Case Officer reviews the evidence and can override the standard formula.
How Care Levels Are Counted
Services Australia counts actual care, not what's in the parenting plan. If your consent orders say alternating weekends but you're consistently having the child for additional midweek nights, you can apply to have the care percentage updated to reflect the actual pattern.
Conversely, if you have orders for shared care but regularly skip your allocated nights, the other parent can apply for a reassessment based on actual care provided.
