I booked the Gold Coast crab catching tour through Klook. The tour group mainly consisted of tourists from Hong Kong, Japan, and Taiwan, with only a few individual travelers. The entire trip lasted two and a half hours and included feeding pelicans, retrieving crab pots, catching small creatures in the mud, and fishing. The captain was humorous and engaging, keeping everyone entertained. However, the "crab catching" simply involved pulling up a pot that I believe was pre-stocked with crabs, but it was still a very fun experience.
The seafood platter I added was of average quality; the crab wasn't fresh and was clearly of inferior grade. I hope this can be improved in the future.
