Your Playground - Waterway Wallis Lake is a major waterway on the NSW East Coast. It is part of the Great Lakes District and boasts the largest area of significant seagrass on the Coast. The Lake is relatively shallow at an average depth of 2.3 meters, which creates a unique playground where large vessels requiring deeper draft cannot operate. There are many islands in the Waterway which create safe ancchorages and calm conditions in any wind condition. The Lake is one of NSW largest Oyster Farming areas and hosts a wide range of fish that attract recreational anglers.
