Family Tax Benefit (FTB) is available to eligible families across Australia, including Perth, and is generally based on your family’s income, care arrangements, children’s ages and residency status. You can claim through myGov linked to Centrelink, either during the financial year or after lodging your tax return. Services Australia may also assess your child’s immunisation, schooling and maintenance details where relevant. Check the current rules and payment estimates on servicesaustralia.gov.au, as the amount and eligibility outcome depend on your individual circumstances.
