Darwin airport might be fine for domestic flights but is not up to scratch as an international airport. With more Tiger and Jetstar flights to Asia via Darwin this airport needs to lift its game. It took nearly an hour to get through immigration and customs on my flight from Singapore which was only 60% full. Only three immigration officers on duty - one queue for all nationalities - while two customs officers eyeing the stationary queue for drug mules. These officers then searched every second bag (welcome to Australia!) before we got into the small and uninspiring terminal where check-in queues can be horrendous.
