Some are getting a green sticker (as mentioned in the article) but who and why is a little murky at the moment.
My 2 cents ...
There are 2 queues for passport & security screening. Let's call them PP-Q1, PP-Q2, SS-Q1, SS-Q2.
PP-Q1 is the general queue, where everyone, whose boarding time is greater than 90 mins is directed to. This queue looks like an obstacle course, snakeing thru the departures area EVEN before entering the automated passport gates. This is the larger automated passport gates area, which stops with the crew gates, just before PP-Q2, which is the "express path" automated passport gates.
PP-Q2 is the priority queue has a seperate entrance. This entrance can be accessed via -
a). inbound transfer pax, who took the QF transfer bus from Gate 15 at Domestic. The transfer bus drops pax at the ground floor, and when the pax come up the escalator, they are presented with the PP-Q2 entrance, which is cordoned off to divert pax to meet with SYD airport ground staff, who then direct pax based on their boarding time to either PP-Q1 or PP-Q2.
b). check in at SYD and depending on the boarding time, you get a green sticker on your BP at check in desk. Then go to the priority queue and show your BP with the green sticker on it to access the priority queue.
The green sticker is applied to those BPs where the boarding time is less than 90 mins (could be 120 mins as well, I'm not sure). If the pax is checking in at SYD check-in counters, these stickers are applied automatically when the BP is issued. However, if you are transferring from a different domestic flight, you may go to the airline check-in desks at SYD to get your green sticker. There have been instances where the SYD airport ground staff have used their better judgement to allow pax those that have boarding time < 90 mins to go thru the PP-Q2 without needing to sight the green sticker.
After one has somehow manoeuvred thru the PP-Q1 and PP-Q2, you will reach the automated passport gates and you do your thing. After this is done, you will be directed to see another SYD ground staff, who then will divert you to SS-Q1 (non-priority) or SS-Q2 (priority). The green sticker on your BP or J/F BP will automatically send you to the SS-Q2 and a no sticker BP regardless of your FF status will send you to SS-Q1 queue.
Now, based on my personal experience, I have always been able to use the PP-Q2 because I always have an express path card with me when I travel international. However, when I reached the point where I'd be directed to the security queue, the express path did not help. The SYD airport staff said that the SS-Q1 is only for J/F or those with green sticker on their BP. This being said, on 08/09 I was able to flash my express path card at SYD and use the priority screening queue with no issues. It's a hit & miss as I see it.
Oh and one more thing - there was a timeout issue at SYD airport last week and the automated passport gates didn't work for most passports. Especially Samoan, Indonesian & some Australian ones too. So pax were sent to manual processing and given the number of departures around the 8-9 am mark, this manual processing queue is quite long. Now, that's one more delay to handle
