Boys Out West Bet Big on Bradfield

The First Real Estate Agency in Sydney’s Newest City


In a bold move that signals their confidence in Western Sydney’s future, Thomas Mosca (28) and Nick Estephen (28) have launched Bradfield International Real Estate (BIRE®), the first dedicated real estate agency in Bradfield. Betting big on the NSW Government’s vision for a globally connected Western Sydney, the duo is staking their claim in the Aerotropolis boom. From Colliers to Founders: A Leap of Faith Formerly Joint-Heads of Colliers’ Sydney Southwest team, Mosca and Estephen have traded corporate stability for entrepreneurship, driven by an unshakable belief in the region’s potential.


“We see this as a once-in-a-lifetime opportunity to lay the foundation for a real estate powerhouse that will shape the next 50 to 100 years,” said Mosca. “We’ve been at the heart of major transactions in the area, and it just felt like the right time to take this step.” But this isn’t just business—it’s personal. “Western Sydney has never been a buzzword to us,” said Estephen. “It’s our home. We were born and raised here, and we’re committed to its future.”

Bradfield: A City of the Future with Local Roots

Bradfield, Australia’s first new city in over a century, may be a blank slate for many. But for Mosca and Estephen, it’s a natural evolution from the Bringelly of their childhood. Their deep-rooted connection gives them a unique perspective on the area’s transformation.


Game-Changing Technology: BIRE® Proprietary Mapping System


BIRE® isn’t just another agency—it’s an innovation leader. The duo has developed the BIRE® Proprietary Mapping System, an industry-first digital platform that collates all Western Sydney Aerotropolis maps into an interactive, multi-layered experience.

“We saw a gap in the market. There was no single platform that provided agents, buyers, and sellers with a seamless way to navigate this complex landscape,” said Mosca. “So we built it.”


This cutting-edge tool integrates planning reference maps with real-time property listings and immersive 360-degree photography, offering an unprecedented way to explore and transact real estate in the Aerotropolis.

“This isn’t just a game-changer for Western Sydney,” added Estephen. “It’s a revolution for the entire real estate industry.”

The Future of BIRE® and the Aerotropolis


With Bradfield set to become a global economic powerhouse, BIRE® is positioning itself at the forefront of this transformation. Backed by a deep understanding of the region and armed with world-class technology, Mosca and Estephen are not just betting big on Bradfield—they’re shaping its future.
