Dentons is a strong choice for clients in the public and private sectors seeking advice on the preparation and negotiation of contracts, maintenance agreements and litigation. The practice group is co-led by experienced Sydney-based partners Marcus Graham, who specialises in the full remit of disputes, from arbitration to expert determinations, and Ourania Konstantinidis, whose expertise in the disputes sphere extends to representing developers, contractors and consultants. The firm’s reach was extended with the arrival of Nathan Abbott from Colin Biggers & Paisley in July 2024 and Matt Coleman from Baker McKenzie in January 2025.
