According to realestate.com.au, a harbourside mansion next door to former Prime Minister Malcolm Turnbull has been listed with a price guide of $85 million to $90 million, more than doubling the price paid by luxury car importer Neville Crichton less than a decade ago. The source describes it as one of Sydney's most expensive residential offerings, and it arrives at a moment when premium Sydney harbour-front real estate continues to attract a buyer pool that operates largely outside the constraints pressing on mainstream mortgage holders.
The Listing in Detail: What $90m Buys at Point Piper
The mechanics behind capital growth of this magnitude are distinct from broader Sydney price movements. Ultra-premium harbour-front properties are not priced by comparable sales in the traditional sense — they are priced by the intersection of irreplaceable outlook, land position, proximity to the CBD, and the depth of the buyer pool at any given moment. Crichton's more than doubling of capital in under ten years reflects this dynamic: the property was always going to benefit from a structurally limited supply of true deep-water harbour frontage within striking distance of Sydney's CBD.

What Ultra-Premium Sales Signal for the Broader Sydney Market
Premium sales at Point Piper and comparable locations establish price anchors that ripple into the upper-mid tier of the Sydney market. Buyers who are priced out of harbour-front in Point Piper frequently redirect to prestige properties in surrounding suburbs, creating a downstream demand effect across Sydney's premium market. For a deeper look at how capital growth and yield perform across different Australian market segments, REAStats tracks suburb-level data including prestige market performance across the country.
Background: Capital Growth, Tax, and the Premium Property Investor
At the ultra-premium level, capital gains tax (CGT) implications on a sale of this magnitude are significant. If Crichton purchased the property as an individual and it has been held for more than twelve months, the 50% CGT discount applies — but on a gain of this scale, the tax liability remains substantial by any measure. This is where sophisticated tax planning, including the use of property depreciation schedules, becomes relevant: over the holding period, depreciation claims on a property of this scale and improvement value can materially reduce the taxable income from the asset year to year. Investors at all price points can draw lessons from this — the tax treatment of premium real estate rewards long holding periods and meticulous asset register documentation.
For those with exposure to Australian property at the investment level, the Australian Property Tax Guide provides a comprehensive overview of how CGT, depreciation, and holding costs interact across different ownership structures. The principles that apply to a $90 million harbourside sale and a $900,000 investment apartment are, in many respects, the same — scale differs, but the tax framework does not. Understanding how depreciation schedules can offset taxable rental income over a holding period is one of the most consistently underutilised strategies among Australian property investors.
Practical Implications for Buyers, Sellers, and Investors
For sellers in the prestige segment, this listing is instructive on timing and price strategy. A vendor willing to guide $85m–$90m after a sub-decade holding period is signalling that the current market remains sufficiently liquid at the top end to support ambitious price expectations. Cash buyers and high-net-worth purchasers in this segment are largely insulated from rate movements, which means premium market dynamics can diverge significantly from what mainstream mortgage-dependent buyers experience.
A harbourside property more than doubling in value in under a decade illustrates the compounding effect of genuine scarcity: when supply is structurally fixed and aspirational demand is consistent, premium waterfront assets have historically outpaced broader city-wide median growth across full market cycles.
At the ultra-premium end of the Sydney market, the $85m–$90m guide for this Point Piper mansion is a data point, not an outlier. It reflects a segment that has consistently produced exceptional capital growth precisely because entry is so restricted. For investors at any budget point, the underlying principle — scarcity of genuinely irreplaceable assets drives compounding growth over long hold periods — remains the most durable lesson this sale has to offer.
