About Us – Vic/Tas

Dial Before You Dig Vic/Tas is a Not For Profit Association that has been in operation since 1989.

The service began in Melbourne under the name Melbourne One Call Service (MOCS) with four members, Telecom Australia, Melbourne Metropolitan Board of Works, Gas and Fuel and the State Electricity Commission. A call centre was initially provided by Telecom Australia and was gradually taken over by MOCS. The privatisation of the gas and electricity utilities saw the further expansion of MOCS and the Association began to include municipal councils, rural water authorities and other telecommunication asset owners.

With continued growth, a national Association was formed in 1999 and MOCS changed its name to Dial Before You Dig Vic/Tas Incorporated.  In partnership with Telstra, a single telephone number, 1100 was adopted nationally in 1999 to assist in producing a more efficient, centralised delivery service.

Dial Before You Dig are encouraged and grateful for the efforts of all that went into the production of these guidelines. The Victorian and Tasmanian Service Guidelines were developed to set the expected safety standards of all those that work in and around infrastructure assets and networks.

The Service Guidelines help to protect the lives of Victorians and Tasmanians and prevent damages to essential infrastructure assets and networks. The Victorian Service Guidelines were officially launched on the 12th June 2009 by Peter Batchelor, the then Minister of Victorian Energy and Resources for Community Development.

These Service Guidelines will ensure the safety of all working in and around infrastructure assets and networks and reduce the risk of damages and disruption to Australia’s essential services.
