Earthmoving and Construction Contractors Operating Across Australia

AUSDIG (SA) Pty Ltd has been involved in the Civil Construction Industry since 2007. South Australian based, owned and operated we offer excavator, plant and equipment hire to construction services in the rail, mining, oil, gas, commercial, domestic, industrial, earthmoving, and civil sectors.

Owner, Zaine Williams, has been involved in the civil industry since 1993, working for some of Australia’s largest civil construction companies before starting his own business. Zaine prides himself as an efficient, safe and competent worker, who works with the client to achieve the desired result in a timely and cost effective manner.

Zaine believes in a healthy working environment, and has been participating in the Healthy Workers’ Program with the Civil Contractors’ Federation and his employees.

As AUSDIG continues to grow and expand, Zaine is passionate about exploring opportunities to help increase employment for Aboriginal and Torres Strait Islander peoples, trainees and apprentices, displaced automotive workers, and local people with barriers to employment. AUSDIG aims to up-skill their workforce through high quality and nationally recognised training to support their team and provide your project with highly skilled and competent operators. We believe in providing opportunities and training to better our employee’s knowledge and experience on the job and for their future.

In doing so, we assist with the monthly Industry Participation Reports and monthly Workforce Participation Reports on some of the current projects that we are working on, which helps us to meet targets and identify future goals and improvements.

We also work with our sister companies Adelaide Plant Hire and Gracescapes to provide additional equipment and landscaping services to those in the Adelaide area.
