RT Edgar Stonnington: Generations of Insight in Melbourne’s Prestige Property Heartland

In the leafy, exclusive streets of Toorak, where grand period estates sit alongside refined contemporary homes and the village buzz of Toorak Road meets quiet residential avenues, one name has long stood as a byword for expertise in prestige real estate: RT Edgar Stonnington.

Located at 10 Wallace Avenue, Toorak, the Stonnington office serves discerning property owners across Toorak, Armadale, Malvern, South Yarra, East Melbourne and the wider Stonnington surrounds. It is the flagship presence of a company with more than 130 years of continuous operation, combining deep local knowledge with the calm authority that comes from generational experience.

A Legacy Built Since 1896

RT Edgar was founded in 1896 by Robert Thomas Edgar, then just 24 years old, as a local agency in Hawthorn. At a time when Victoria’s property market was still recovering from financial collapse, Edgar showed remarkable foresight. The business grew steadily with Melbourne’s expanding suburbs. His son Jack later joined, and the firm became RT Edgar and Son. Through the challenges of the Great Depression and the Second World War, the company continued to expand, helped by figures such as Colin Anderson, into Armadale, Malvern, Kew, Toorak and the CBD.

In 1990 the office relocated to Toorak, returning to the suburbs that had always been central to its identity. By 1996 it had settled at its present home on Wallace Avenue. Today the network spans 16 offices across metropolitan Melbourne, the coast and regional Victoria, yet the Stonnington team remains firmly rooted in the local community.

The company’s stated values — reliability, care, credibility and decisiveness — continue to guide every transaction. As the official About Us page notes, Robert Edgar’s original vision of service built on these principles still shapes the business more than a century later.

Specialists in Prestige Homes

RT Edgar Stonnington specialises in the full spectrum of high-end residential property: grand historic estates, architecturally significant contemporary homes, and sophisticated apartments. The team understands what makes each property distinctive and, equally importantly, who the right buyers are.

Directors and auctioneers including Jeremy Fox, Sarah Case, Mark Wridgway, Warwick Anderson, Anthony Grimwade, Jack Edgar and others bring decades of collective experience. Many clients have stayed with the firm for decades — sometimes across generations — because the service prioritises clear strategy, discretion and results over hype.

The office delivers sales by private treaty and auction, comprehensive property management, leasing services and project marketing for developers. Recent market activity shows consistent strength: in the twelve months to mid-2026 the Stonnington team recorded substantial sales volumes with strong median prices reflecting the quality of stock they handle.

Deep Local Knowledge, Statewide Reach

What sets the Stonnington office apart is its combination of hyper-local insight and the resources of a well-established network. Agents know the nuances of particular streets, the appeal of certain architectural styles, and the preferences of buyers moving within or into the area. When the ideal match sits elsewhere in the RT Edgar network, referrals are made with confidence.

The team is also committed to developing the next generation of agents, ensuring fresh energy sits alongside long-held expertise. Property management is a core strength, with a dedicated head of property management and specialists focused on securing quality tenants and protecting owners’ assets.
