The house used in filming this movie looked familiar!

The only thing I know is:

"It took eight weeks to construct the Warr's house for the film."

and

"The house in the film was built at a property in Myponga Beach, South Australia and was planned to be taken down after filming. Owners of the property, however, persuaded producers to leave the house and surrounding areas intact and it has now been converted into the successful Bed and Breakfast "Brooklyn Farm - Joe's House"."
