What Sinclair Brook does
Sinclair Brook is an Australian privately held development and project management firm headquartered in Melbourne, founded in 2004 by Phil Burns. The firm provides end-to-end services across the property development lifecycle, structured around three core offerings: Development Management (site acquisition, due diligence, feasibility modelling, planning approvals, financing, and sales coordination), Project Management and Superintendent services (pre-construction management, contractor procurement, construction supervision, and defect management), and Advisory/Transaction Management/Capital Solutions (project origination, JV structuring, debt and equity capital raising across the capital stack). It serves property developers, landowners, capital partners, and institutional clients including religious and not-for-profit organisations. Notable project mandates include Australia 108, Melbourne Square, Market Square Adelaide, Gen Fyansford, Pavilions Blackburn Lake, and Windsor Park.
The firm operates across five offices in Melbourne (HQ), Sydney, Adelaide, Suva (Fiji, via SB Fiji), and Abu Dhabi (Middle East), with related entities including Sinclair Brook Developments and SB Capital supporting co-investment and holding structures. Its go-to-market is sales-led B2B professional services, reliant on industry relationships, referral networks, and a demonstrated project delivery portfolio. Pricing is project-specific and quote-based; fees are negotiated per scope rather than published. The firm does not publicly disclose revenue, financial details, or employee counts beyond an 11–50 headcount band.
Underlying tooling consists of Estatemaster feasibility software augmented by a proprietary internal budget and cashflow management model that tracks project cost, forecast cashflow, costs to date, and future expenses throughout the development lifecycle. The firm's competitive positioning rests on senior leadership pedigree (cumulative 20–40+ years of experience across law, finance, construction, and development, including prior senior roles at Jennings Industries, Lend Lease, Mirvac, and Woolworths Group), multi-jurisdictional reach, and repeat JV relationships with partners such as ICD Property, OSK Property, Wilbow Group, and Hiap Hoe. The firm is privately owned by its founders, with no disclosed institutional investors, parent company, or funding rounds.
