Staff-to-Child Ratios in Australian Childcare: Complete Guide
Staffing is the single largest cost in running a childcare centre — and the single biggest headache. Wages consume 55% to 85% of a centre’s total operating costs, according to the ACCC’s Childcare Inquiry, with a median of 70%. Get your staffing model wrong, and every other number on your P&L suffers. Get it right, and you have the foundation for a profitable, compliant, high-quality service.
This guide covers the mandatory educator-to-child ratios, how they differ between states, the qualification requirements, and — critically — what all of this means for your centre’s financial performance and market value.
The National Ratios: What the Law Requires
Under the National Quality Framework (NQF), every centre-based childcare service in Australia must maintain minimum educator-to-child ratios at all times during operation. These are not optional guidelines — they are legally enforceable standards.
The national minimums for long day care centres are:
Birth to 24 months: 1 educator for every 4 children (1:4)
24 to 36 months: 1 educator for every 5 children (1:5)
36 months to preschool age: 1 educator for every 11 children (1:11)
These ratios are calculated across the entire service, not room by room. Every educator counted towards the ratio must be physically present and directly engaged in educating and caring for children — a staff member on a break, doing admin, or preparing food does not count.
ChildcareLink Insight: In practice, most well-run centres staff above the minimum ratios. A centre operating at bare minimums has zero buffer for sick days, breaks, or unexpected absences — which means one educator calling in sick can put you out of compliance by 9 AM. Budget for at least 10–15% above minimum staffing at all times.
State-by-State Differences That Catch People Out
While the NQF sets the national framework, several states apply stricter ratios for specific age groups. If you are buying or operating across multiple states, these differences directly affect your staffing costs and rostering model.
Victoria applies stricter ratios for toddlers: 1:4 for children aged 24 to 36 months (compared to 1:5 nationally). This means a Victorian centre with 20 toddlers needs five educators in that age group, versus four educators in most other states — a 25% increase in toddler-room staffing.
NSW, South Australia, Tasmania, and Western Australia apply 1:10 for children aged 36 months to preschool age, compared to 1:11 in Queensland, Victoria, the ACT, and Northern Territory.
Western Australia applies a 1:13 ratio for children over preschool age (or 1:10 if kindergarten children are in attendance), while most other states apply 1:15.
For buyers evaluating centres in different states, these variations can shift your wage line by 5–10% before you change anything else. Always model your staffing costs using the specific ratios for the state where the centre operates.
Qualification Requirements: Not Just Headcount
Meeting the ratios is about more than numbers — it is about qualifications. The NQF requires:
At least 50% of educators counted towards ratios must hold, or be actively working towards, an approved diploma-level education and care qualification.
The remaining educators must hold, or be actively working towards, at least an approved Certificate III in education and care.
Additionally, every centre with 25 or more children must have access to a degree-qualified early childhood teacher (ECT) for specific hours, depending on the number of children enrolled.
This qualification mix matters financially. Diploma-qualified educators command higher wages than Certificate III holders, and early childhood teachers earn significantly more again. Your staffing budget needs to reflect the real cost of the qualification mix — not just the headcount.
The Workforce Crisis: Why Ratios Are Harder to Meet Than Ever
Australia’s childcare sector is facing a genuine workforce crisis. According to Jobs and Skills Australia, the sector needs 21,000 more qualified ECEC professionals to meet current demand. The Australian Childcare Alliance reports that 90% of centres are experiencing difficulty filling positions, with the average time to fill a permanent role stretching to 12 to 16 weeks.
The sector employs over 173,000 educators nationally, but below-average retention rates mean operators are constantly recruiting. Low pay relative to comparable professions, demanding working conditions, and limited career progression have been driving educators out of the sector for years.
The Federal Government’s Worker Retention Payment is the most significant attempt to address this. From December 2024, eligible educators received a 10% wage increase above the applicable award rate. From December 2025, this rose to 15% above award — translating to at least $155 per week more for a typical educator. The government is funding this increase directly, with a fee growth cap to prevent providers passing costs to families.
On top of this, the Fair Work Commission applied a 3.5% minimum wage increase for FY2025/26, and states like NSW are offering scholarships of up to $35,000 for early childhood education degrees.
ChildcareLink Insight: For buyers, the staffing crisis cuts both ways. A centre that has retained a stable, qualified team is worth significantly more than one with chronic vacancies and agency reliance. When we assess centres, staff tenure and turnover are among the first things we look at — they tell you more about the business than the P&L does.
How Staffing Costs Hit Your Bottom Line
With wages consuming a median of 70% of total operating costs, even small changes in staffing efficiency compound rapidly.
Consider a 60-place centre in Sydney. Under minimum ratios, you might need roughly 8 to 10 educators on the floor at any given time (depending on the age mix), plus a centre director and potentially a cook, cleaner, and administrative support. With the 15% Worker Retention Payment increase, your all-in annual wage bill for a centre of this size could sit between $900,000 and $1.3 million.
That wage bill is largely fixed — it does not flex with occupancy until you are dramatically under-enrolled. A centre at 60% occupancy pays nearly the same wages as one at 90% occupancy, because the ratios must be maintained regardless. This is why occupancy is such a critical driver of profitability — the staffing cost floor is high, and only revenue from enrolled children can cover it.
The implication for valuations is direct. Staffing costs flow straight through to EBITDA, which is the primary metric buyers use to value a leasehold childcare business. A centre with high agency costs, excessive overtime, or above-market wages will show a lower EBITDA — and therefore a lower sale price — than a centre with the same revenue but a well-managed, stable team.
Practical Staffing Strategies for Operators
Understanding the ratios is step one. Managing them profitably requires a staffing model that balances compliance, quality, and cost.
Model your roster around your actual enrolment pattern, not your licensed capacity.
Most centres have predictable peak and trough periods throughout the day and week. Staggering educator start and finish times to match these patterns is one of the most effective ways to manage costs while maintaining compliance.
Build a reliable casual and relief pool.
Every centre needs access to qualified casuals who can step in at short notice. The cost of a casual educator is almost always less than the cost of being caught short and either breaching ratios or closing a room.
Track your staff-to-revenue ratio, not just your staff-to-child ratio.
The regulatory ratio tells you what is legal. The financial ratio tells you what is sustainable. If your total wage costs consistently exceed 75% of revenue, your operating model needs attention.
Factor staffing into your franchise decision.
Franchise groups sometimes offer recruitment support, shared relief pools, and centralised rostering systems. Independent operators need to build these capabilities themselves.
What This Means for Buyers and Investors
If you are considering purchasing a childcare centre, staffing should be at the top of your due diligence checklist. Here is what to look for:
Staff tenure.
A centre where the average educator has been there three or more years signals a healthy workplace culture and lower future recruitment costs. A centre with 50%+ annual turnover is a red flag.
Agency reliance.
Centres that depend heavily on agency staff are paying a premium — agency rates can be 30–50% above direct employment costs. This suppresses EBITDA and often signals deeper retention issues.
Qualification compliance.
Verify that the centre actually meets the 50% diploma / 50% Certificate III requirement. Non-compliance can trigger regulatory action.
Wage positioning relative to award.
Centres paying significantly above award may be doing so to retain staff in a tough market — or they may have a structural cost problem. Understand why before you model forward.
The Bottom Line
Staff-to-child ratios are not just a compliance checkbox — they are the single biggest driver of your operating cost structure and, by extension, your centre’s profitability and market value. The national ratios set the floor, state variations add complexity, and the current workforce crisis means filling those positions costs more and takes longer than ever before. Operators who build stable, well-managed teams have a genuine competitive advantage — both in the quality of care they deliver and in the value of the business they are building.
