The plan was always to run fresh produce straight into Asia via the business park. The airport will also side on to the highway (freeway?), being built, going straight past it making it easier to bring South and West QLD and Northern NSW produce directly to the airport for overseas transport. The master plan for the apron area at Welcamp is HUGE.
What will, however, be interesting is watching aircraft trying to line up with the runway at the minima on the offset RNAV into 12. They may also need to fix up the PAPI on 12 before they try and get a 747 in there, it has been showing a fly up indication now for about 1 year.
