From www.heffron.com.au: Turning 65 is significant for superannuation as it allows individuals to fully access their superannuation funds without restrictions and offers the most favorable tax treatments, such as tax-free pension payments.
While people aged 60 can access their super through a “transition to retirement” pension, they face limitations compared to those at 65 who can also make contributions.
Additionally, turning 65 requires individuals to be mindful of the transfer balance cap on retirement phase pensions, which could affect tax implications if their pension exceeds the current threshold.
