Harry Potter star lists home in NSW Southern Highlands town of less than 4000 people

British-born actor and Harry Potter star Miriam Margolyes has listed her regional property in the NSW Southern Highlands with a multi-million dollar price tag.

The three-bedroom architecturally designed home set on 62.5ha sits on a spectacular site with views from the highlands to the sea.

Listing agent Bradley Cocks of Drew Lindsay Sotheby's International Realty Bowral has a listing price guide of $3.95 million to $4.2 million for the Robertson property.

The 84-year-old actor discovered the property while filming Babe in 1995. She voiced the character of Fly the sheep dog in the Oscar-nominated film which was filmed in the area.

Her other roles have included that of Professor Sprout in the Harry Potter films and more recently Ladies in Lavender with Maggie Smith and Judi Dench.

The property, known as Yarrawa Hill, is a secluded retreat that she has shared with her Australian partner Heather Sutherland.

It features an architect-designed contemporary home with a feature double-height great room with Pacific Ocean views captured through the floor-to-ceiling windows.

This main living area includes a central fireplace perfect for cooler months, vaulted ceilings and expansive decks.

The large kitchen has a large walk-in pantry, modern appliances and stainless steel finishes.

It features views across the Illawarra escarpment, and adjoins the dining area which has deck access.

The home is ideal for having guests stay, with each of the three bedrooms having their own sitting area, bathroom and peaceful outlook.

A separate lower-level suite features underfloor heating, an open fire, and a secluded deck.

Described as a property of "cinematic beauty" the land component includes a eucalypt forest, rainforest and paddocks.

There is plenty of native wildlife that has also made the extensive property home including wallabies, lyrebirds, wombats and local birdlife.

While the property is an ideal private retreat it is close to Robertson, a small hamlet that is most famous for its Big Potato, which has struggled to find a buyer in recent years.

It is also a short drive to the Southern Highlands centre of Bowral, which is home to cafes, restaurants and lifestyle stores alongside medical facilities.

Some of the South Coast's prettiest towns are also within reach, with easy access to Kiama and Gerringong.

The actor, who has dual British and Australian citizenship also owns an investment property in Bondi Beach which is currently leased.
