Melbourne-based property developer brothers Tony and Steven Sass have quietly picked up three adjoining clifftop mansions to create a record-setting $61 million family compound in the elite holiday playground of Sorrento, on Victoria’s Mornington Peninsula.

The brothers and co-founders of Oreana Property Group have inked three trophy deals worth $24 million, $16 million and about $21 million across three neighbouring addresses on coveted Point Nepean Road. The $24 million purchase has already settled.
