About Us

A new rural business, Southern Downs Ag – SDA - was formed in March of 2015, to support the men and women of the Warwick region, who make their living on the land.

SDA was created by Marcus Stewart, Steve Nelson, Stuart Judd and Neil Shelley to service Warwick and the surrounding areas for all heavy machinery repair, sales and service.

Marcus specialises in the repair and maintenance of tractors, hay and harvesting equipment of all models and varieties. Steve repairs and services all types of agricultural equipment along with the repair and maintenance of heavy earth moving equipment.

Marcus and Steve are both very qualified mechanics with many years of experience and can also repair and service any size truck, from utes to semi-trailers.

Rob Collman joined the team in November 2015. Rob is the head of the sales team at SDA and has many years of experience in the agricultural industry.
