Harrison Infrastructure Group is the result of the merger of Highland Infrastructure Group Pty Ltd and The Harrison Group (Qld) Pty Ltd, which took effect on the 1st of July 2014.

Established in 1996, The Harrison Group (Qld) opened with an office located in Brisbane. Company demand for their services saw the need for expansion into Toowoomba in a consulting capacity in 2005 and in 2006 an office was opened.

In 2008, Highland Infrastructure Group was created in Toowoomba as a sister company to The Harrison Group, offering design expertise with a small and highly experienced team. The success of Highland Infrastructure and the increasing reputation as a supplier of choice, lead to the opening of a Rockhampton office in January 2011. Further expansion into regional Queensland soon followed, with Bundaberg office opening it's doors in May 2011 and the Roma office (in conjunction with THGQ) in March 2012.

Highland Infrastructure Group purchased Lockyer Designs in July 2010 and it has continued its success in the Lockyer Valley region. In 2013, Highland Infrastructure Group joined the Lockyer Designs office space, furthering our support to the area.
In February 2015 our satellite office at the Gold Coast moved to new premises at Southport.
