  • Jack Mason is a property professional with over 15 years’ multifaceted experience across project marketing, sales, valuation, and property development.

    Jack started his career in real estate in commercial property management at Raine & Horne where he learnt the fundamentals of property, including relationships between tenants and landlords, managing leases, legal standings, and the property itself.

    Jack’s career then moved into valuations, where he undertook a Bachelor of Commerce at the University of Canberra and completed a Post Graduate Diploma in Property at the University of South Australia — all while working hands-on at CBRE.

    Primarily focusing on residential and commercial development valuations, Jack then moved into a senior role at Independent Property Group as Developments Manager in Project Marketing.

    The skills learnt in this role along with his previous experience led to his appointment as Development Director with Nikias Diamond, and the subsequent formation of Bronte Group in 2019. In his current role as Managing Director, he has successfully managed the delivery of over $750 million in property value.

    Jack’s understanding of commercial valuation, project feasibility and finance combined with his experience in off-the-plan sales management provides a wealth of knowledge in the field of property development.

  • Dimitri Nikias has four decades of experience in the property and development sectors with deep and wide expertise in project financing, property marketing, design development, building approvals, valuation and feasibility.

    The son of a builder, Dimitri started his career in property after completing school when he was awarded a cadetship with LJ Hooker in 1981. He studied a Diploma of Valuation at the Canberra Institute of Technology and further education followed by receiving his Bachelor of Valuation in Business from the Royal Melbourne Institute of Technology (RMIT).

    While working for LJ Hooker and later RL Davis and Co, Dimitri leased, sold and/or developed 600,000 square metres of commercial space valued at around $1.2 billion. In 1997, Dimitri joined the Nikias group of companies, and in 2004 together with George Diamond formed Nikias Diamond. Since then, with Dimitri as Development Manager, the firm has developed and built - for Nikias Diamond and clients - commercial space valued at more than $500 million as well as 300 residential dwellings with a total value of around $80 million, including obtaining finance for those projects, for both Nikias Diamond and our clients.
