Sentinel Invests $700m in Darwin
September 18, 2025
Sentinel Property Group has grown its extensive footprint in the Northern Territory with the purchase of tenanted industrial facilities in the Darwin Business Park at East Arm for $57.4 million.
Sentinel, which owns Casuarina Square as part of its circa $700 million portfolio in the Top End, has acquired the facilities at 21 and 31 O’Sullivan Circuit, East Arm. The transaction was negotiated by JLL’s Ben Hegerty, Gavin Bishop, Joel Scully, Sean Thomson and Mark Jagla.
The East Arm assets comprise three modern industrial facilities with a total gross lettable area (GLA) of 22,280 sqm. The properties are arranged over two leasehold lots with a total site area of 12.92ha. They are leased long term to high-quality tenants including Toll Energy, Team Global Express (TGE) and the Federal Government. The weighted average lease expiry (WALE) is 5.47 years.
Darwin Business Park is in the industrial precinct suburb of East Arm, which is centrally positioned close to rail and port terminals between both Darwin and Palmerston population centres.
Sentinel CEO Warren Ebert said the Group held an enviable property portfolio in Darwin, including the 2022 acquisition of the city’s Casuarina Square Shopping Centre from GPT Group for $418 million.
“Sentinel have been highly active in Darwin for almost a decade,” Mr Ebert said.
“We are heavily invested in the Territory, not only owning and managing the largest shopping centre Casuarina Square but assets including CBD office buildings, a sports club and other commercial buildings.
“We are long in Darwin because it’s the closest port to Asia, with massive resource projects and a growing defence presence and infrastructure.
“Investment conditions in the NT have also improved since the CLP under Chief Minister Lia Finocchiaro came to power last August. We plan to increase our investment activity. One of the government’s outstanding achievements has been a 90 per cent reduction in crime.”
31 O’Sullivan Circuit, East Arm. comprises a circa 2005 built industrial facility, consisting of three warehouses, two of which are connected by a breezeway and include cold room and office facilities, along with substantial concrete hardstand and expansion land. TGE occupy two buildings while the other facility is leased to the Department of Home Affairs. The site area is 84,400 sqm.
21 O’Sullivan Circuit comprises a circa 2015 built industrial facility, comprising warehouses, temperature-controlled storage, office, mezzanine and canopy together with substantial hardstand. The property is leased to Toll Energy and has a site area of 44,800 sqm.
