Hello Christel.
Thank you for your feedback. Without knowing the exact circumstances of your transfer it is hard to comment. eg where were you going, was your flight late etc? To Port Douglas, we schedule departures every 45 mins to coincide with clustered flights. It takes about 30 mins to get off a flight and collect bags, as such we consider 45 mins is manageable and most arriving passengers have sufficient time to meet their transfer service. We also do a looped service to the CBD about every 30mins. If your flight was late and you missed the service you were booked on you would have had to wait for the next service, another 45 mins (if going north). Without info we cannot advise further. There is always a wait period for shuttle services. Sometimes a bit longer than others. It may have been better for you to have booked a private transfer and you would have been on your way immediately. We hope you enjoy your stay here and enjoy the sunshine mother nature is putting on for us.
