Bombah Broadwater is the southernmost of three brackish lakes that make up the Myall Lakes system, located on the New South Wales coast between Port Stephens and Forster, approximately three hours north of Sydney. It sits within Myall Lakes National Park, which is designated a Ramsar wetland of international significance. The Broadwater lies in the flow stream of the Myall River, giving the water a distinctive tannin-stained orange colouration. This staining extends partway into the middle lake, Boolambyte Lake, before the water clears.

The lake is well suited to touring and overnight camping trips by kayak. Water conditions are generally flat, but because the Broadwater is large and shallow, moderate winds can generate choppy surface conditions quickly, making weather forecasting an important part of trip planning. Paddling is possible year-round, though winter nights can be cold by Australian standards.

Several access points serve the Broadwater. The Nerong Boat Ramp is reached by turning off the Pacific Highway onto Whimbrel Drive (signposted to Nerong) approximately 30 km north of the Karuah River bridge, then following Whimbrel Drive to Egret Street. From the ramp, paddlers travel out through Nerong Inlet into the Broadwater. On the eastern shore, Mungo Brush Boat Ramp on Mungo Brush Road (20.5 km north of Tea Gardens bridge) provides a concrete ramp with nearby camping and toilet facilities, though this site is also popular with water skiers. Bombah Point, accessible from Bulahdelah via Bombah Point Road (approximately 10.5 km, partly unsealed), has a concrete floating wharf with pump-out facilities and public courtesy moorings, along with a caravan park with a small convenience store; the nearest public boat ramp to Bombah Point is at Korsman's Landing. A vehicular ferry connects the southern access road from Hawkes Nest and Tea Gardens to Bombah Point, operating daily from 8am to 6pm for a fare.

Wildlife in the area includes kangaroos, sea eagles, whistling kites, goannas, and dingoes. The national park setting and Ramsar status reflect the ecological significance of the lakes system.
