On the Dolphin Sands sand spit, about 16km from Swansea (and well signposted from the highway north of town), Melshell is a quirky caravan on a working oyster farm. Grab your dozen and head for the seats atop the dunes overlooking Melshell's leases in the Swan River. It has glasses if you BYO wine.
