About Us

We’re a boutique Buyer and Vendor Advocacy based in Brighton East, specialising in helping clients buy and sell quality properties across Melbourne’s East and South East.

GNA Property was founded with a simple goal — to empower our clients through truly independent advice and representation. Whether you’re buying your next home or selling your current one, we put your interests first, tailoring our service to achieve the best possible outcome for you.

For buyers, we work closely with you to identify the right property, develop a clear strategy, and negotiate with confidence. For vendors, we act as your independent advocate throughout the sales process — managing agents, providing strategic guidance, and ensuring your campaign achieves maximum results.

With strong industry relationships, deep local knowledge, and an insider’s understanding of the Melbourne property market, we give our clients access to premium on- and off-market opportunities — and the peace of mind that every decision is backed by experience and expertise.
