Where the port actually is
The container terminals sit at Fisherman Islands, at the end of the Port of Brisbane Motorway past Lytton. Empty container parks are clustered nearby through Lytton, Hemmant and Pinkenba, which is why so much Brisbane warehousing sits along the eastern corridor.
For a delivery in Coopers Plains or Acacia Ridge, the leg is a straightforward Gateway run. The variability is at the terminal end, not on the road.
