Melbourne has taken Sydney’s crown as home to the most expensive house ever sold in Australia, with landmark Toorak estate Coonac selling for about $150 million in a low-key deal that has eclipsed the previous national house record by some $20 million.

The deal was inked for what is widely regarded as one of Victoria’s best homes. The landmark 1867-built Coonac was sold by Financial Review Rich Lister, billionaire property developer and former Toll Holdings boss Paul Little and his businesswoman wife Jane Hansen, who is the chancellor of the University of Melbourne.
