The Department of Communications released a discussion paper exploring the effectiveness and some of the challenges of the current system on Tuesday. 

The review is being conducted to ensure that an improved service can be provided in the future.

The national emergency response number was established in 1961 and attracts nine million calls each year. 

Originally the service was established when voice calls from landlines were prominently used. 

Today, about two thirds of triple zero calls are made from mobile phones. 

The triple zero service is a used by all Australians when they need emergency assistance.

The review will focus on the Commonwealth-regulated national triple zero operator and Commonwealth regulation relevant to the triple zero emergency call service. 

It will also work closely with the state and territory emergency service organisations.

Individuals and organisations are invited to contribute to the review by completing an online survey or making a written submission.

Submissions will be accepted until August 22,  and the report is expected to be completed by March 2015.
