The only reference to it in the Jepp is in Terminal AU-18 (3).
The only time I would imagine a controller clearing you a specific approach (with reference to Sydney) is if you had not specified DME equipment on board your aircraft in the flight notification, obviously then you could only use the PRM - Y with use of GNSS.
