The national average median weekly cost for 50 hours of centre-based childcare rose by $10 a week between 2020 and 2021, from $530 to $540.

Tasmania recorded the highest weekly price hike, rising by $24, followed by Queensland at $16 and South Australia at $15.

The national average for 50 hours of family day care services rose by $8 per week between 2020 and 2021, with Tasmania reporting a $31 per week rise, while the ACT reported a $26 price drop.

Meanwhile, Victoria and the Northern Territory reported the biggest increases in recurrent early childhood spending during the past two financial years, rising by $2321 and $1859 per child respectively.

The federal government’s recurrent early childcare spending rose by $1.4 million in that time.

Every jurisdiction except the Northern Territory reported an increase in serious incidents of injury, trauma or illness at childcare services during the past two financial years, with the biggest incident spike, 1719, in NSW.
