A useful cost comparison for families should include housing, electricity and gas, water, groceries, transport, childcare, school costs, healthcare, insurance and regular activities. Compare the total weekly or monthly cost rather than focusing only on rent or mortgage repayments, and include one-off expenses such as moving, deposits, car repairs and school supplies. Check whether changes in location affect commuting time, childcare availability or access to services. Actual costs will depend on your household circumstances, so use recent bills and quotes where possible and check official Australian government guidance for available assistance.
