Wiley, I came through Brisbane International last week and it's just as bad as you remember. The crew lane for immigration is mixed with the 'Assisted Passengers' and Express Lane so be prepared for a looooooonnnng wait.
The 3 Jumbos worth of passengers were through the normal lanes long before any of the crew had got near the front. In the end they moved us all over to the vacant normal lanes. Reminded me why I try to avoid Brisbane.
