Is this domestic or international? Hobart???

as Gold, on domestics you can use the premium security lane
In Syd international, the priority lane is business and first - all airlines. It is unclear if status can use these lanes. But at least at Syd departure security seems to work these days
i have not seen a priority customs lane for a very long time. Unfortunately as the morning queue is often long - with QF cabin crew often deliberately queue jumping which is not a good look imho.
