Malcolm Turnbull is selling his $18 million-plus property

THE richest MP in federal parliament, Malcolm Turnbull, and his wife, Lucy, have listed an $18 million-plus Point Piper harbourfront investment property.

The house, designed by Michael Suttor and completed in 2003, is adjacent to the couple's $50 million residence.

The marketing of the townhouse-style three-bedroom house has begun with an inspection from the merchant banker Mark Burrows. The three-level house has 400 square metres of living space.

The Turnbulls have considered selling the Wunulla Road property for several years. Its former tenants include Lynton Taylor and Edward Jewell-Tait. Its listing coincides with a break in its reputed $5000-a-week tenancy.

The sale comes at a time when the resilience of Sydney's increasingly overcrowded prestige market has attracted international interest.
