Sunny Coasters heading off for family reunions both south and north will make up a fair percentage of Bonzas passengers
But people don't do that
every day. And then only to where Bonza flies? Because if they need to go anywhere else, they can just go via Brissie. Relying on very discretionary travel in a very price sensitive market is asking for trouble imo. To establish a viable route you need consistant travel. How many people have a need to go between Milidura and Sunny Coast (or anywhere else for that matter) often enough?
