Security focus had begun years prior to the games. The focus went beyond hostile vehicle mitigation (HVM) measures to include various other identified security risks. Perimeter security measures were aligned with the recently implemented Australia and New Zealand Counter Terrorism Committee (ANZCTC) strategy for the protection of places of mass gatherings. A core element of this strategy was the effective and practical implementation of HVM measures at key locations. As the Australian partner of Delta Scientific, Knight Brothers Pty Ltd secured the contract for the vehicle barrier systems in late 2017 and liaised closely with organisers to ensure that specific security measures could be achieved through implementing Delta's unique barrier systems.

"Barriers protected major event venues including the main games stadium, Gold Coast Convention Centre, the Athletes Village and critical street closures throughout the Gold Coast area," reports Matthew Knight, director of Knight Brothers. "It was important for the Games' operations that access for emergency and authorized vehicles was maintained through the duration of the event.

"The primary use of the 20-foot (6m) Delta portable barriers was in public areas where ground fixation or in-situ HVM measures were not practical or achievable," Matthew Knight adds. "Barriers were deployed in a variety of configurations in order to meet security and access needs. This included direct access points as well as heightened temporary security check points with stringent vehicle inspections undertaken by Australian Defense Force personnel. Secure access points at other locations were operated by contracted security personnel."

Delta's MP5000 portable barricades can be installed in 15 minutes or less to protect streets, entrances or wide expanses such as access to pedestrian areas. They protect people and critical infrastructures at public events and places of mass gathering, such as the Commonwealth Games. These mobile deployable vehicle crash barriers carry a recognized K8 rating (M40 ASTM rating). They lower to let vehicles through but, when raised, they will stop a 6800 kg vehicle traveling 64 km/h. At the Games, stand-alone battery operated hydraulic systems with supplementary solar power charging and remote-control operation activated the barriers and allowed a high rate of vehicle throughput in meeting specific operational requirements.
