The mansion has a heated 25-metre lap pool and a lagoon-style pool.
The property is called Kooeloah, which means 'home of the dolphins'.
It was listed for $15 million in 2012 so if the rumours are true, Hemsworth bagged himself a bargain.
The home has sweeping ocean views and is spread over six separate buildings.
The home has eight bedrooms, 11 bathrooms and a golf green.
Kooeloah sits on a 10-acre property with ocean and rainforest views.
The home is in the sought-after coastal area of Broken Heads.
Other features include a billiard room, home office, gymnasium and yoga space.
The NSW home features a 3,000 bottle, fire proof wine cellar.
The home has a private road leading to the beach.
The home was built in 1989 for retired film and television producer Suinee Wong Lomas and Eric Lomas, the retired CEO of Singapore’s The Yellow River Network.
