Dyball Reserve is a small boat ramp located in Swanhaven on Swan Lake, near Sussex Inlet in New South Wales. The slipway is best suited to light craft such as kayaks and canoes rather than larger motorised vessels.

Swan Lake itself is a popular watersports destination, offering opportunities for sailing, stand-up paddleboarding, and water skiing, with protected shallow zones ideal for paddlers.

The reserve provides a convenient access point to the lake for those launching lighter watercraft.
