GPT Group secures $380 million Brisbane CBD office tower
GPT Group has announced the acquisition of 66 Eagle Street, Brisbane by its sector-agnostic, value-add partnership for total consideration of $380 million plus acquisition costs. The transaction extends the partnership’s total deployment to over $500 million in Gross Asset Value (GAV) since its establishment in February 2026, and broadens the platform into core office alongside its existing student living and logistics investments.
Russell Proutt, Chief Executive Officer and Managing Director
“Brisbane’s Golden Triangle remains one of GPT’s highest-conviction office sub-markets, where we already own and manage 111 Eagle St and Riverside Centre. With Brisbane office leasing fundamentals strengthening, material under-renting in the asset and limited forecast supply into the CBD, this investment aligns with our strategy to co-invest with our partners and leverage our operational capabilities to deliver strong returns.”

Inside the deal — what GPT is buying and why it matters
Asset profile at a glance
| Metric | Detail | Metric | Detail |

| Levels | 23 | Acquisition price | $380 million plus acquisition costs |

Discount to replacement cost
The acquisition price reflects a significant discount to replacement cost, according to the announcement. While no specific percentage has been disclosed, this pricing dynamic is positioned as a key value signal for the partnership, suggesting the asset can be acquired below what it would cost to build an equivalent tower in the same precinct today.
GPT’s role in the asset
GPT will undertake investment management, leasing, and property management services for 66 Eagle Street. This positions the Group as an active operator within the partnership rather than a passive capital allocator, consistent with its broader platform strategy.
GPT’s wholesale fund acquisitions of Sunshine Plaza and Macarthur Square earlier in 2026 followed the same capital-light management fee model, with GPT retaining leasing and property management mandates while deploying third-party capital at scale.
Understanding GPT’s value-add partnership model
A value-add partnership is a co-investment structure in which GPT manages assets alongside capital partners, aiming to generate returns through operational improvements and leasing upside rather than simply holding stabilised assets. The platform is sector-agnostic, meaning it is not restricted to a single property type.
Since its establishment in February 2026, the partnership has deployed capital across three distinct asset classes:
- Student living
- Logistics development (including the Blacktown logistics development, which is included in the GAV figure at on-completion value)
- Core office, with 66 Eagle Street as the latest addition
The breadth of asset classes covered in under a year signals a rapidly maturing platform. With total deployment now exceeding $500 million in GAV, the partnership has scaled at pace. Importantly, 66 Eagle Street represents the partnership’s entry into core office, and GPT’s existing operational familiarity with the Brisbane CBD reinforces the rationale for this being the platform’s first office investment.
GPT’s 1H 2026 interim results show group AUM expanding 4.6% to $41.6b over six months, with $1.7b in gross transactions underpinning the platform’s accelerating deployment pace across asset classes.
Brisbane office fundamentals and the investment case
Why Brisbane, why now
GPT has identified Brisbane’s Golden Triangle as one of its highest-conviction office sub-markets. The Group already owns and manages two assets in the precinct, 111 Eagle Street and Riverside Centre, providing established operational familiarity with the local leasing environment.
According to CEO Russell Proutt, three factors underpin the investment thesis for 66 Eagle Street specifically: strengthening Brisbane office leasing fundamentals, material under-renting within the asset (representing potential upside as leases roll and market rents are captured), and limited forecast supply into the Brisbane CBD. The announcement does not quantify these factors beyond management’s stated assessment.
Transaction structure and GPT earnings impact
Key terms of the transaction are as follows:
- The acquisition will be financed by the partnership through equity and non-recourse debt, with no recourse to GPT’s balance sheet.
- The transaction is not expected to have a material impact on GPT’s 2026 earnings.
- Financial close is targeted for November 2026.
- The transaction remains subject to Foreign Investment Review Board (FIRB) approval.
The announcement does not disclose the specific equity and debt split within the partnership financing structure. No additional financing detail has been provided beyond the above terms.
