Peter Diamantakis is a seasoned real estate professional with an unwavering dedication to delivering exceptional service and achieving outstanding results.
Peter Diamantakis is an award-winning real estate agent specialising in Pakenham and Officer, with nearly 10 years of experience helping local homeowners achieve outstanding results.
Recognised as realestate.com.au’s 2025 Top Agent for Pakenham, Peter is currently ranked Pakenham’s #1 agent based on recent suburb sales and client reviews. He was also inducted into the Barry Plant Pinnacle Club in 2026—an achievement reserved for the network’s Top 20 agents—and was recognised as the #1 sales agent within his Harcourts network in 2024.
Peter has built his reputation on honest advice, strategic marketing, strong negotiation and clear communication throughout every stage of the selling process. Rather than applying the same approach to every property, he takes the time to understand each owner’s individual circumstances, priorities and goals before creating a tailored strategy designed to achieve the strongest possible result.
Supported by the dedicated three-person Team Diamantakis, Peter ensures every campaign receives consistent attention, proactive buyer follow-up and regular communication. His sellers benefit from access to an extensive local buyer database, relationships with buyer advocates and the wider reach of the Barry Plant office network across Pakenham, Officer, Berwick, Drouin and Warragul.
Peter’s selling strategy can also provide homeowners with the opportunity to test the market privately through a structured off-market campaign before committing to a full public launch. This allows qualified buyers to be introduced to the property early, while providing sellers with genuine feedback and the possibility of achieving an outstanding result without upfront marketing expenses.
With more than 200 five-star client reviews and an extensive record of successful sales throughout Pakenham and the surrounding areas, Peter’s results are backed by measurable performance. His clients consistently recognise him for being professional, genuine, trustworthy, reliable and a strong negotiator.
Whether assisting a first-time seller, managing a complex campaign or taking over a property that has previously struggled to sell, Peter remains focused on providing straightforward advice and creating the best possible outcome for his clients.
For homeowners considering selling in Pakenham, Officer or the surrounding areas, Peter offers proven local knowledge, a personalised strategy and the support of an experienced team from the initial appraisal through to settlement.
