CORNERSTONE COMMERCIAL

Cornerstone Commercial – Sales & Leasing with a Developer’s Mindset

Cornerstone Commercial is a boutique commercial real estate agency focused on sales and leasing across South East Queensland. Led by Principal and Director Kristy McMillan, the agency stands apart for its practical, development-informed approach that helps clients position their assets to attract strong tenants and secure premium outcomes.

With a background rooted in commercial property development, Cornerstone offers a unique edge—balancing real-world asset experience with a personable, hands-on style. Kristy is directly involved in every transaction, giving clients the benefit of genuine care, straight-talking advice, and a business owner’s attention to detail.

Cornerstone Commercial services a wide catchment across the Moreton Bay region and beyond, including high-growth corridors like Caboolture, Brendale, and North Lakes, with select assets managed as far north as Mackay. Whether it's leasing a neighbourhood retail centre or selling a freestanding industrial facility, the team brings sharp negotiation skills, strong local knowledge, and a commitment to clear communication throughout.

Kristy and the team are known for forging long-term relationships rather than transactional wins. Clients trust them not just to market a property, but to consider the broader strategy—from tenant mix and lease terms to presentation and positioning. That developer’s mindset is embedded in everything they do.

For commercial property owners looking for a refreshingly personal, results-focused agency that doesn’t just list and wait, Cornerstone Commercial offers a smarter, more grounded alternative.
