Australia has never had a "legal" retirement age for pilots. Before the 1989 Pilots Strike (or dispute - or a rose by any other name you want to call it) the pilots union in collusion with the airlines dictated the age 60 forced retirement.
That was later over-turned and now there is no age limit. Recently a 68 year old former captain has just been employed as a F/O. Best of luck to him, too.
