From the report
The Ballina Byron Gateway Airport operator recorded an annual total of 343,581 passenger movements for the 12 month period ending 24 November 2012.
Airservices Australia (Airservices) data indicates that in the twelve months to December 2012, there were a total of 15,037 aircraft movements.
Just under the 350,000 for the establishment of a Class D Tower. Given that some 30 months has elapsed since the last review then it is probable that the trigger has been well and truly reached.
Based on the numbers, control tower for Ballina?
