Our Story - so far

Company founders Clint & Sarah McClure established COSA Engineering in the small Western Victorian town of Harrow in 2006, providing labour and engineering services to the farming and burgeoning local mining industry. A move to Horsham in 2008, the purchase of an existing crane company and the opening of new depot facilities quickly built an integrated crane and engineering company serving a broad cross section of Western Victoria industries.

Further expansion followed in 2013 with the purchase of a crane company at Katherine in the Northern Territory, which at the time contained only a small fleet of vehicles. Over the next two years the business expanded to service a vast area across the top half of the NT requiring a corresponding upscaling and upgrade of the crane fleet and ultimately culminated in the creation of a second NT depot in Darwin during early 2015.

The COSA Group was formed in mid-2015 when a Perth based plant hire company (Jones Mining Innovation Rental Division or JMI) was acquired and merged into the three existing crane and engineering businesses. Specialising in the hire of mobile plant for the mining, civil and heavy construction industries the addition of JMI has created a unique business able to support diverse range of industry sectors across the entire continent.

However despite this rapid growth and with operations now based across three states and located in either capital cities or large regional centres the country origins of the COSA Group, where locals expect honesty, quality and personalised service, is to this day the mantra that drives our versatile and experienced team.
