The Abu Dhabi Investment Authority (ADIA) has sold its stake in a prime Brisbane office tower, One One One Eagle Street, for AUD284m (€201m).

ADIA sold the interst to its co-investor, GPT Wholesale Office Fund (GWOF), one of Australia’s largest office owners.

GWOF has now lifted its ownership to 66.67%. GPT, developer of the tower and manager of the wholesale fund, has the remaining 33.33%.

ADIA was GPT’s joint venture partner when the project, located in Brisbane’s sought-after Golden Triangle, launched in 2008 during the global financial crisis.

Costing AUD670m to develop, it was completed in 2012. Some of the largest blue-chip companies and top legal firms now occupy the building’s 63,800sqm of commercial space.

GWOF fund manager, Martin Ritchie, said the fund exercised a call option to acquire ADIA’s stake.

β€œThis transaction represents a very rare opportunity for GWOF to increase its investment in this highly sought-after, premium-grade office asset,” he said.

The acquisition brings GOF’s gross assets to AUD6.5bn. 

A source told ΒιΆΉΣ³»­ Real Estate that ADIA’s rationale to sell was similar to those of other long-term foreign institutional investors in Australia, such as Singapore’s GIC, which have sold down assets in the country.

β€œIt is hard to say where ADIA will deploy the proceeds of the sale,” the source said.

β€œIt could be in one of its other Australian investments or it could repatriate the funds for investment overseas.”

ADIA has a number of investments in Australian real assets, but One One One Eagle Street was the sovereign wealth fund’s only investment with GPT.

A year ago, ADIA partnered Australian infrastructure specialist Hastings in a , a high-voltage electricity network, from the NSW Government for AUD10.3bn. Through its Tawreed Investments unit, ADIA has a 20% stake in TransGrid.

In 2013, ADIA paid a record-breaking AUD800m Tourism Asset Holdings, Australia’s largest hotel owner.
