Wetlands and estuary country on the edge of New Norfolk

Overview

New Norfolk sits in the upper Derwent Valley, about 35 kilometres north-west of Hobart, where the river broadens into a quieter estuarine landscape. Around the town, the natural character is shaped less by rugged high country and more by water, mudflats, reeds and sheltered river margins, with the River Derwent Marine Conservation Area beginning here and continuing downstream.

One of the standout protected areas in this setting is Murphys Flat Conservation Area, a wetland on the southern shore of the Derwent between Granton and New Norfolk. Though relatively small at about 66 hectares, it holds an outsized role in the river system, containing a substantial share of the remaining wetlands in this part of the Derwent estuary and combining marshes, underwater grasses, tidal flats and reed beds in one compact area.

Highlights

The appeal of this part of New Norfolk is its low-lying estuarine scenery. Broad river reaches, fringing wetlands and tidal flats give the area an open, layered look, with calm water, reeds and mudflats changing character with the light and the tide. It is a softer landscape than many Tasmanian bush settings, but a very distinctive one.

Murphys Flat is especially notable for the way several wetland forms sit together in a narrow stretch of river edge. That mix of marsh, shallow aquatic vegetation and intertidal ground creates a rich visual mosaic and explains why this section of the upper estuary feels so ecologically alive.

Best Time to Visit

Spring through autumn is generally the most rewarding time to spend time around New Norfolk’s river and wetland country, when milder weather and longer daylight make the estuary easier to appreciate. Wetland areas are often at their liveliest when bird activity is high and the river margins are green.

That said, this landscape is not purely seasonal. Even in cooler months, the combination of open water, tidal flats and river-edge vegetation gives the area a quiet, atmospheric character that suits a slower visit.

Plants and Animals

This part of the Derwent is important habitat rather than just a scenic river frontage. Murphys Flat supports marshes, submerged grasses, reed beds and backwater areas that shelter fish, platypus and waterfowl, while the wider River Derwent Marine Conservation Area provides habitat for species including black swans, native ducks, frogs, snakes, fish and a wide variety of invertebrates.

Birdlife is one of the strongest natural features around New Norfolk’s wetland edge. Murphys Flat is known for abundant birds, including large numbers of black swans, and it also supports foraging habitat for significant species such as the wedge-tailed eagle, white-bellied sea-eagle, swift parrot, masked owl and great crested grebe. The reserve also serves as a nursery area for sandy flathead and shelter for juvenile native fish.

Culture and Heritage

At Murphys Flat, cultural heritage is part of the landscape as well as the ecology. The area includes the ruins of an 1820s inn and the site of Lieutenant Governor Arthur’s Marsh Farm, one of Australia’s earliest land reclamation works. The same area is also reported in the management statement as having been on a travelling route for two Aboriginal tribes.
