we went on aug 6 on CX785 and though it was busy, we walked fast to the visa counter (were in row 30- but with 3 small kids). My wife went to the immigration lines. She was then moved over to the APEC queue (over to the far right) as she had children. It looked like others were doing the same. I have an APEC card so we could have used this queue anyway but we were through in 15 mins....
