What Castlerock Property does

Castlerock Property Pty Ltd is a Melbourne-based, family-owned Australian property fund manager founded in 2002 that specializes in the acquisition, development, and management of commercial real estate leased predominantly to government tenants in 'beyond-the-CBD' and regional locations. The company operates two core unlisted investment funds, the Castlerock Government Property Fund and the Castlerock Services Australia Fund, with combined funds under management of $658 million across 20 properties encompassing approximately 1.2 million square metres of lettable area at a 98% portfolio occupancy rate. Its tenant roster is heavily concentrated in federal and state government agencies, including the Queensland Government, Victorian Government, Australian Taxation Office, Centrelink, Parks Victoria, Solar Victoria, and the Country Fire Authority, with weighted average lease expiries approaching nine years.

Castlerock's competitive differentiation rests on an integrated in-house 'Own, Develop, Manage' operating model that spans property acquisition, development delivery, construction management, design, and ongoing facilities management under a single organizational structure. The company's development capability is supported by in-house design and construction teams led by a Director of Projects with delivery experience across more than 35 buildings, and is reinforced by specialist partnerships with architects (WMK Architecture, ARTAS), steel fabrication firms (Dynamic Steel Frames), and Indigenous cultural partners (GunaiKurnai Land and Waters Aboriginal Corporation, The Torch). Portfolio assets routinely achieve premium sustainability credentials, including 6-star NABERS energy ratings and 5-5.5 star Green Star certifications, and the company achieved ISO 14001 environmental certification in October 2025.

The business generates revenue through three primary streams: recurring fund management fees on approximately $658M of managed assets, rental income from owned or co-developed properties, and episodic property development margins and capital gains on assets developed for sale or held within the funds. Distribution is conducted through a proprietary investor portal (invest.castlerockproperty.com.au) and direct relationship management by a Communications and Investor Relations team, targeting wholesale and sophisticated investors seeking exposure to government-covenanted regional property. Castlerock is led by CEO Adam Bronts (with the company since 2003) under Chairman Hank Bronts, supported by a recently appointed CFO (Michael Wilde, ex-Cromwell Property Group CFO with $12B FUM oversight) and a team of approximately 37 employees. The company is privately held by the Bronts family with no external institutional ownership.
