In Australia, there’s a discount available on private health insurance premiums for individuals who are under 30 years old through some providers. This discount is called the Age-based Discount (ABD) and encourages young people to get private health insurance by offering them a reduced premium. The discount is 2% for each year the policyholder is aged under 30, capped at 10% for those aged 18-25. The age-based discount doesn't apply to people aged 18 to 29 years who are covered as a dependent on a family or single parent policy. However, the discount can stay in place until the policyholder reaches age 41, when it reduces at a rate of 2% per year until it reaches 0%.
