Family Tax Benefit (FTB) is financial assistance for eligible families caring for dependent children. Part A is generally based on family income, the number and ages of children, and your level of care, while Part B may provide extra help to some single parents or families with one main income. Services Australia also considers residence, child support and other circumstances, so the amount and eligibility can vary. You can check the current rules and estimate your entitlement through myGov or servicesaustralia.gov.au.
