About OC Real Estate

From a Shared Vision to a Household Name

Alex Ouwens and Nathan Casserly came together in 2014 with one shared belief. Real estate should feel different. More personal. Built on trust and driven by care.

From day one, they set out to create an experience where people came first and every interaction was shaped by integrity. That meant building genuine relationships, delivering meaningful results, and creating a workplace where great people could thrive.

What began as one office in Adelaide has grown into one of Australia’s most respected independent agencies. Guided by passion, innovation, authenticity and unity, we continue to help people move forward with confidence.

Or as we like to say, let's make it happen.

Putting people first has always shaped who we are. From clients and team members to the communities around us, our focus is on supporting others through life’s important moments with genuine care and unwavering integrity.

Alex Ouwens, Co-Founder

We’ve always been willing to challenge the way things are done. Not for the sake of being different, but to find better ways to grow, lead and deliver something meaningful for the people who trust us.

Nathan Casserly, Co-Founder

What We Do Best

Our award-winning sales team is recognised amongst the top agents in South Australia. With a focus on strategy, market knowledge and an honest, personalised service, we help sellers and buyers navigate every step of the property process with clarity and care. The results that speak for themselves.

We take a forward-thinking approach to every property under our care. With smart systems, clear communication, and a responsive team, our property managers go beyond the everyday routine tasks to guarantee reliable tenant management, reduced vacancies, and long-term value. From long-term leases to holiday rentals, we deliver a more considered experience for landlords and tenants alike.

Selling at auction should feel sharp, focused and, above all else, stress-free. Our in-house auctioneers do just that. Bringing the right balance of strategy, presence and negotiation expertise to every campaign, we guide the whole process from the first call to the final bid. We build momentum, spark competition and create the conditions for strong results.

We partner with developers to turn vision into value. Backed by real estate expertise and project marketing insight, our team tailors each strategy to the scale, stage and story of the development. From early planning through to sell-out, we connect projects with the right buyers through smart positioning and market intelligence.
