Leonie O'Brien

Leonie is the driving force behind Stone Real Estate Macarthur’s marketing – where big-picture strategy meets on-the-ground execution. With a Bachelor of Business (Marketing) and a background across property, finance, and tech, she knows how to turn smart ideas into real results.

As part of the senior management team, Leonie plays a key role in shaping the direction of the business – bringing creative thinking, commercial clarity, and a deep understanding of what drives growth. From building brands that stand out to crafting campaigns that actually convert, she works side-by-side with agents to make sure every listing, every post, and every piece of marketing hits the mark.

 Her work doesn’t just look good: it gets homes sold, portfolios grown, and businesses noticed.

Proudly local, Leonie is raising her family in Macarthur and knows firsthand how powerful great marketing can be in connecting with the right audience. She also gives back as part of the fundraising and marketing teams for Camden Women’s Shelter – because making an impact matters.

Creative, strategic, and relentlessly effective, Leonie brings fresh thinking and serious marketing muscle to the Stone team – helping agents grow stronger brands and deliver better results, every single day.

The Stone Macarthur Community Fund puts aside part of every sale or lease to support local charities and initiatives.
