Family Tax Benefit (FTB) is a Centrelink payment that helps eligible families with the cost of raising children. Part A is generally based on the number and ages of children, family income and care arrangements, while Part B may provide extra help to some single parents or families with one main income. You can claim through Services Australia, either as regular payments during the year or as a lump sum after lodging your tax return. The amount and eligibility depend on your circumstances and are usually balanced against your actual annual income, so check the latest rules at servicesaustralia.gov.au.
