Buying Property in Toorak: Heritage Mansions, Significant Trees, and the Tax Consequences of Melbourne's Most Expensive Suburb

Toorak is Melbourne's most expensive suburb by median house price and by far the most consequential from a transaction-tax perspective. At typical Toorak values, stamp duty alone runs into hundreds of thousands of dollars and annual land tax assessments for investment holdings can exceed $100,000. The Section 32 matters here not because individual overlays are exotic — most are the same Stonnington regime seen in Armadale and Malvern — but because the dollar consequences of every clause are amplified by the price level.

This guide covers the Section 32 and Contract of Sale issues specific to Toorak (postcode 3142, City of Stonnington, with a small pocket in City of Melbourne).

Toorak at a glance

• Council: primarily City of Stonnington. A small section north of the Yarra River is under City of Melbourne.
• Postcode: 3142
• Typical buyer: established wealth, corporate executives, downsizers from multi-lot Toorak homes into Toorak Village apartments, international buyers.
• Dwelling mix: large Victorian-era mansions, inter-war grand homes, significant contemporary architect-designed houses, apartment stock concentrated near Toorak Village and along Toorak Road.
• Typical median values (verify at time of purchase): houses ~$5–$10 million and higher for prestige stock; Toorak Village apartments ~$1–$3 million.

Tax: the defining buyer issue

At Toorak values, transaction tax is a major line item:

• Stamp duty on a $7 million purchase exceeds $430,000 at current Victorian rates. The first-home-buyer exemption does not apply.
• Land tax on a $5 million site value produces annual land tax assessments above $50,000 for investors and absentee owners. See our land tax guide.
• Vacant Residential Land Tax (VRLT) applies to residences unoccupied for more than six months. Extended to all of Victoria from January 2025. Holiday-home Toorak owners need to be aware.
• Foreign purchaser additional duty applies for non-citizen buyers.

Heritage Overlay coverage

Toorak carries extensive Heritage Overlay (HO) coverage across the Victorian and Edwardian residential streets. Unlike neighbouring Boroondara, Stonnington does not use an A–D heritage grading system — heritage controls are applied through precinct-specific citations and individual-building listings.

Practical consequences:

• Demolition is restricted on HO-covered properties. The economic thesis of buying a tired mansion for knock-down-and-rebuild may be foreclosed.
• External alterations require permits and heritage-impact assessment.
• Heritage-compliant replacement materials are substantially more expensive than contemporary alternatives.

Significant tree controls

Toorak's streetscape is characterised by mature canopy, and significant trees are a protected asset under the Stonnington planning scheme. Tree removal and works near protected trees require permits. An arborist report at due-diligence stage is worth the fee when renovation is planned.

Yarra River frontage

The Yarra River forms part of Toorak's northern boundary. Properties on the river bank or in the lower- elevation streets may carry Land Subject to Inundation Overlay (LSIO), Environmental Significance Overlay (ESO), and in some cases Erosion Management Overlay (EMO) for escarpment sites. See our Kew guide for the escarpment-risk framework.

Section 173 Agreements

Large Toorak lots are often subject to Section 173 Agreements under the Planning and Environment Act 1987 (Vic). These can record:

• Restrictions on further subdivision.
• Ongoing heritage-permit obligations.
• Tree protection and vegetation management requirements.
• Drainage, access, or other infrastructure contributions.

Every Section 173 Agreement on the title must be obtained in full and read.

Subdivision reality

Toorak's large 1,500–4,000 m² lots look superficially attractive for subdivision or development. In practice, heritage controls, significant tree protections, neighbourhood-character policy, and Section 173 Agreements make subdivision approval materially harder than in less-regulated suburbs. Before modelling a subdivision thesis into the purchase price, get a pre-purchase town planner assessment.

Other Toorak-specific contract issues

• Apartment OC risk— Toorak Village and Toorak Road apartments carry the usual inner-south cladding and OC risk profile. See our South Yarra guide.
• Heritage-listed fences, walls, and gates require permits for alteration.
• Private school corridortraffic around St Catherine's and nearby schools.
• Foreign Investment Review Board (FIRB) approvals for foreign purchasers.
