It is against the law to compulsorily retire most employees in New South Wales. This means that it is now possible for most employees to continue working past any previous compulsory retirement age.
Compulsory retirement is when an employer forces an employee to retire because of their age.
This is a very general statement and hasn't yet been interpreted by the courts. It could, for example, be against the law to make you pass tests or assessments that younger employees don't have to pass. These types of tests or assessments should be conducted fairly whatever age you are. Naturally, you can still choose to stop working at the old compulsory retirement age, or indeed at any other age. In general, it must be your choice not your employer's choice when you retire - provided, of course, that you are still capable of doing your job.
