Any recent experience with priority security lane in SYD when not in business? For what it's worth, Star website lists SYD as having Gold Track:

If so, is it a sticker on your boarding pass or something similar? I have seen people in the queue with those, but I'm not sure what airline they were.
When I flew out on NZ104 on Saturday the security queues were almost as heaving as during that horror period after Covid (though I think they were moving a bit quicker) so I was definitely glad to be in the priority line.
