Port Campbell is a quaint little fishing village. Nowadays it is the summer destination for many Australians, but it still hasn't lost its charm.
We recommend eating dinner in 12 Rocks. If you go in summer (December-January), it's a good idea to arrive an hour before dinner, as it's usually full and it takes a while to be seated and served. Still, it's worth it. The food is outstanding and if you sit outside or close by, you'll be able to watch an amazing sunset.
The Scotch Fillet is very good, as is the fish (seafood basket), which is the speciality of the town. Dinner will run you about 15-20 AU$ per dish.
