Childcare ratios and regulations in South Australia

Last reviewed: 8 November 2026. Checked against the Education and Care Services National Regulations (Part 7.6, regulations 318 to 339, and regulations 256 and 257), ACECQA’s ratio table and Education Standards Board guidance, on 8 November 2026.

Quick answer

South Australia uses the national ratios unchanged: 1:4 from birth to 24 months, 1:5 from over 24 months to under 36 months, 1:11 from 36 months to preschool age and 1:15 over preschool age (regulation 123). Its own rules are in Part 7.6 of the Regulations. The most used is regulation 325A: a centre can count an educator who steps away for up to 30 minutes in total a day, as long as they can return to the children immediately. The regulator is the Education Standards Board (ESB).

This page covers what is different in South Australia: short absences, preschool teacher rules, school-age care qualifications and the services ESB regulates outside the NQF.

The legal framework in South Australia

South Australia applies the Education and Care Services National Law through the Education and Early Childhood Services (Registration and Standards) Act 2011, and uses the Education and Care Services National Regulations. Regulation 318 applies Part 7.6 to South Australia. The Education Standards Board is the regulatory authority for NQF services, including long day care, family day care, preschools and outside school hours care.

Childcare ratios in South Australia

Age of childrenRatio in SASource
Birth to 24 months1:4r 123(1)(a)
Over 24 months and under 36 months1:5r 123(1)(b)
36 months or over, up to preschool age1:11r 123(1)(c)
Over preschool age1:15r 123(1)(d)

Unlike NSW, Victoria, Tasmania, the ACT and WA, South Australia does not change any band. The SA ratio calculator applies these figures across the service. See the age groups guide for how “preschool age” is defined.

Short absences: regulation 325A

Nationally, regulation 122 counts only educators working directly with children. Regulation 325A relaxes this for centre-based services in SA. A centre is taken to meet the ratio while an educator is not working directly with children if:

For a rating assessment the service is taken to comply with regulation 123. The 30 minutes is a total for the day, not 30 minutes per break, and it does not change the duty of adequate supervision. Queensland, Tasmania and WA have similar but different rules. Compare them in the ratios guide.

Early childhood teachers in preschools: regulation 324

For preschools, regulation 324 applies instead of the national qualification rule in regulation 126. Regulation 319 defines a preschool as a government preschool or a preschool program run by a non-government school.

Long day care centres follow the national early childhood teacher requirements.

Outside school hours care qualifications: regulation 321

For children over preschool age in a centre-based service, regulation 321 requires the first of every 2 educators in the ratio to be a qualified educator, and at least one qualified educator at the service to be a first qualified educator. Both terms refer to qualifications on ACECQA’s South Australian lists for educators working with children over preschool age.

Other South Australian provisions

Services outside the NQF

ESB also regulates South Australian early childhood services that sit outside the NQF, which it calls residual services. Examples include occasional care, in-home care, rural and mobile care, and individual family day care. They are regulated under a modified version of the National Law set out in Schedule 2 of the Education and Early Childhood Services (Registration and Standards) Act 2011, and under service-specific standards.

Can an educator take a break without being replaced in SA?
