It is called a sub-class 410 temporary residents visa for retirees, (over 55), valid ten years, (recently upped from four) and allows unlimited work. Best one could do over 45, max age for immigration unless filthy rich, (or on a boat!).
This sub-class visa no longer available. Replaced by a 405 visa which requires oodles of dosh both to get initially and subsequently to renew.
Still hope for
PR/citizinship one day. No plans to ever leave, it is just too nice for that!.
