Child Care Subsidy — 100 hours per fortnight (recognised participation)

What Is This Payment?

The 100-hour participation rule is the standard activity-test cap inside the federal Child Care Subsidy scheme. The rule database tags it as a Group B benefit with eligibility_enabler as its result role, sitting in the Child Care Subsidy parent cluster. Unlike the 3 Day Guarantee floor, this rule is gated on a positive participation test rather than applied automatically, which makes it the primary lever for working and studying families.

The administering body is Services Australia. Recognised activities are defined in policy notes: paid employment, formal courses, vocational training, structured volunteering, paid leave (including maternity, paternity, and long-service leave), and approved job-search activity all count. Routine household work, parenting one's own children, and unpaid help around a family business do not count. The hours figure is reported through myGov by the parent, and Centrelink can request evidence such as employer letters, study load statements, or volunteering rosters during compliance reviews.

The design intent is to align subsidised hours with the practical demands of working or studying parents. A working parent typically needs around 9 to 10 hours of care per work day to cover commute time and travel margins; the 100-hour cap supports five subsidised days per fortnight. The entitlement scope is per child and ongoing while participation stays above 48 hours per fortnight. The rule's effective_date is 5 January 2026, the same day the 3 Day Guarantee floor was introduced; before that date the older activity test bands of 50, 72, and 100 hours per fortnight applied.

How Much Can You Get?

The amount block is defined as type: eligibility_only with period none. The rule produces no direct cash. The dollar value is realised by feeding into the percentage rules (90%, taper, or zero) and multiplying out to actual hours of attendance.

To convert the cap into dollars, the headline figures from the percentage rules combine with the 100-hour ceiling:

• Centre-based day care: $14.63 per hour cap at the 90% rate gives 0.9 × $14.63 × 100 = $1,316.70 per fortnight of subsidy capacity per child when participation is above 48 hours.
• Family day care: $13.05 per hour cap at the 90% rate gives 0.9 × $13.05 × 100 = $1,174.50 per fortnight.
• Outside school hours care: $12.81 per hour cap at the 90% rate gives 0.9 × $12.81 × 100 = $1,152.90 per fortnight.

Audit recipe: confirm the lower-participating parent records more than 48 hours per fortnight (so this rule applies), confirm the child is under 13 in approved care, look up the percentage tier from family income, then multiply percentage × min(actual fee, hourly rate cap) × min(actual hours, 100). For example, a centre-based family on the taper at 78% (income $145,000) using 90 hours of care per fortnight at $15 per hour pays subsidy = 0.78 × $14.63 × 90 = $1,026.95 per fortnight; the cap of 100 is not reached because actual attendance is only 90.

The marginal value of this rule over the 3 Day Guarantee floor is up to 28 extra subsidised hours per fortnight per child. At centre-based caps and 90%, that translates to about $368.68 per fortnight per child, or roughly $9,585 per year. For a two-child household using approved care at full participation, the marginal value approaches $19,000 per year compared with the 72-hour floor.

The cap is per child, not per family. Each enrolled child has its own 100-hour ceiling. The cap is also a maximum, not a target; a child attending only 70 hours per fortnight is subsidised at 70 hours regardless of whether the participation gate qualifies the household for the higher cap. The rule has no multiplier, no reduces_if, and no date_windows. The only scope-limiter is the effective_date of 5 January 2026; the expiry_date is null in YAML, so the rule remains in force through 2025-26.

Eligibility Conditions

The eligibility block is an all set, so every item must pass.

1. Approved child care: approved_child_care = true. The provider must be CCS-approved; informal arrangements such as relative or au-pair care fail this gate regardless of how many hours the parents work.
2. Child age: child_age < 13. The CCS scheme covers children under 13; secondary-school-aged children fall outside the scheme even when both parents are working full-time.
3. Activity threshold: recognised_participation_hours_fortnightly > 48. Strictly greater than 48 hours per fortnight. A household at exactly 48 hours falls under the 3 Day Guarantee floor instead.

Required fields are the approved child care flag, child age, and recognised participation hours per fortnight. The exclude block is empty. Three sibling rules sit on the conflicts list — the 3 Day Guarantee 72-hour floor, the exemption 100-hour rule, and the ATSI 100-hour rule — ensuring only one hours-cap rule applies in any given fortnight.

The affects block links this rule to the 90% standard rate rule with a requires_context effect. The same logic extends to the taper and zero percentage rules. The activity hours rule and the percentage rule are evaluated together by the engine; the dollar subsidy is the product of the two outputs plus the rate cap by service type.

Two practical considerations matter for the participation gate. First, the household figure is the lower of the two parents' recognised hours. A high-income parent at 70 hours of work per fortnight cannot single-handedly lift the household into this rule when the partner is on extended unpaid leave (zero hours); Centrelink uses the lower number. Second, for couples whose participation hovers near the 48-hour boundary, accuracy matters. A parent reporting 49 hours one fortnight and 47 the next produces a different cap each time; some families miscount casual shifts or volunteer hours and discover the discrepancy at year-end reconciliation when activity records are reviewed.

How To Apply

Application metadata defines a single channel: online. The 100-hour participation cap applies automatically once a CCS claim is approved and the family's recorded activity hours exceed 48 per fortnight for the lower-participating parent. The activity record is updated through myGov, typically when starting or changing a job, enrolling in a course, or setting up a structured volunteering arrangement.

Evidence requirements are explicitly listed in the rule:

• activity evidence — payslips, employment letters, study load confirmations, volunteering rosters, or other documents showing recognised participation hours per fortnight

Two practical tips. First, the activity figure is the parent's own declaration in myGov, but Centrelink can audit it. A parent who reports 60 hours per fortnight of paid work should keep three months of payslips on hand in case of compliance review. Discrepancies between declared and actual hours can produce a CCS debt at year-end reconciliation. Second, leave entitlements count differently across employer types. Salaried employees on annual leave or paid sick leave can include those hours; casual workers without leave entitlements lose the corresponding hours from the activity figure during unpaid leave periods.

Rule-Based Scenarios

Scenario 1: dual-income full-time couple at the 100-hour cap

Damir and Coralie both work 76 hours per fortnight in office roles and use a centre-based day care charging $14.63 per hour for their 3-year-old. The lower of the two participation figures is 76, well above the 48-hour split, so this rule applies. Family income is $145,000, putting them at (145,000 − 85,279) / 5,000 = 11.94 floors to 11 steps, so percentage = 90 − 11 = 79%. With actual attendance at 100 hours per fortnight, subsidy = 0.79 × $14.63 × 100 = $1,155.77 per fortnight. The 5% Centrelink withhold reduces fortnightly payment to provider to $1,098 with the rest reconciled at year end.

Scenario 2: studying parent with part-time work

Theo is studying a postgraduate degree at a load equivalent to 50 hours per fortnight while doing 20 hours per fortnight of casual tutoring. Total recognised participation is 70 hours per fortnight, above 48, so this rule applies. His partner Genevieve is at home with their younger baby and has 0 recognised hours. The lower figure (Genevieve's 0 hours) governs, and the household actually falls under the 3 Day Guarantee floor with a 72-hour cap, not this 100-hour rule. Theo's high participation alone does not lift the household into this rule.

Scenario 3: single parent at full activity, fully eligible

Eitan is a sole parent working 65 hours per fortnight as a graphic designer. His 4-year-old attends family day care for 80 hours per fortnight at $13.05 per hour. Recognised participation is 65 hours, above 48, so this rule applies. Family income is $72,000, well within the 90% tier. Subsidy = 0.9 × $13.05 × 80 = $939.60 per fortnight. The cap of 100 is not reached because actual attendance is only 80 hours. Eitan's CRN is on file with the provider, who bills the subsidised gap fee directly.

Scenario 4: high earner with two children, taper applies

Anika and Reuben earn a combined $230,000. Both work 80 hours per fortnight. Their twins (twin sisters aged 4) both attend centre-based care for 90 hours per fortnight each at $15 per hour. Lower participation figure is 80 hours, above 48, so this rule applies for both children. (230,000 − 85,279) / 5,000 = 28.94 floors to 28 steps, so taper percentage = 90 − 28 = 62%. Per-child subsidy = 0.62 × $14.63 × 90 = $816.55 per fortnight. The higher-rate-second-child rule lifts the second twin's percentage by 30 points to 92% (capped at 95%), adding $395 per fortnight more for the second twin's enrolment, and the 100-hour cap applies to both twins independently.

Common Mistakes

• Adding both parents' hours together: the 48-hour split looks at the lower-participating parent, not the household sum. Some families add 60 + 30 to get 90 and assume they qualify; they do not, because the 30-hour figure governs and falls under the 72-hour floor.
• Counting commuting time as participation: only the contracted work hours, study contact hours, or formal volunteering hours count. A parent commuting 5 hours per week to a 30-hour workplace cannot inflate their figure to 35; participation is the engagement itself, not transit time around it.
• Missing the strict greater-than at 48: the rule uses > 48, not >= 48. A parent at exactly 48 hours per fortnight falls into the 3 Day Guarantee floor (72-hour cap), not this rule. The boundary tightness catches families who plan their activity figure to land precisely on 48.
• Forgetting that paid leave still counts: a salaried employee on paid annual leave continues to record their normal participation hours during leave. Casual workers on unpaid time off lose those hours. Some salaried workers under-report by stripping out leave fortnights, which incorrectly drops them into the 72-hour floor.
• Counting unsupervised volunteer-type activity: "structured volunteering" needs to be with a recognised organisation that can vouch for hours. Informal community help, hobby projects, and ad-hoc favours do not satisfy the activity test even if they consume real time. The structure requirement traps parents who substitute hobby work for formal participation.
• Stopping the activity update after a job change: a parent who reduces hours below 48 per fortnight remains attached to this rule until the activity record is updated through myGov. The system does not auto-detect a hours drop; until the parent reports the change, CCS is calculated against a 100-hour cap that the family no longer qualifies for, producing a year-end debt.

Related Rules And Interactions

The conflicts list and affects list in YAML define interaction behavior:

• Child Care Subsidy — 3 Day Guarantee (72 hrs/fn) — direct conflict; the floor that applies when recognised participation is at or below 48 hours per fortnight.
• Child Care Subsidy — 100 hrs/fn (valid exemption) — direct conflict; same 100-hour cap but reached through an approved exemption rather than through participation.
• Child Care Subsidy — 100 hrs/fn (ATSI child) — direct conflict; same 100-hour cap automatically available to Aboriginal and Torres Strait Islander children regardless of activity.
• Child Care Subsidy — 90% rate — affects link with requires_context; the percentage rule that pairs with this hours cap to produce the actual fortnightly subsidy at low family incomes.
• Child Care Subsidy — taper rate — middle-income percentage rule that combines with this 100-hour cap for families above the $85,279 lower threshold.
• Child Care Subsidy — higher rate for second child — works alongside this 100-hour cap to lift the percentage on second and younger children under 5 by up to 30 points (capped at 95%).

These are direct relationship declarations from the rule and should be treated as deterministic for this policy version. The four hours-cap rules are mutually exclusive in any given fortnight; the engine selects whichever rule's gates are satisfied for the household at assessment time.
