Cost of Raising a Child in Sydney

Birth to age 18, moderate lifestyle — what parents in Sydney actually spend, by category.

Published 2026-09-07 · Global KidCost Calculator

Sydney is Australia's most expensive city to raise children — housing (especially near good schools) and childcare lead the bill. But strong public services (Medicare, free public schools) and a generous, means-tested Child Care Subsidy soften the load.

Total to raise one child, birth to 18, on a moderate budget with public school: $230,000 USD ( (A$345,000 AUD)).

Where the money goes: 8 categories

Category	Birth–18 cost (USD)	Share
Housing & Space	$59,800	26%
Food & Nutrition	$36,800	16%
Festivals & Social Etiquette	$34,500	15%
Education & Childcare	$27,600	12%
Travel & Entertainment	$23,000	10%
Clothing & Daily Goods	$20,700	9%
Healthcare & Insurance	$16,100	7%
Prenatal & Infant Setup	$11,500	5%

Housing is typically the largest single line item, followed by education and local services. Your real mix depends on neighborhood and lifestyle.
