The National Injury Insurance Scheme (NIIS) Advisory Group has convened in Sydney to discuss the progression of developing a comprehensive insurance scheme for catastrophic injuries.

The NIIS Advisory Group was formed in late 2011 by Federal Minister for Workplace Relations, Bill Shorten, with an aim to establish a scheme to cover the lifetime care and support needs for people who experience a catastrophic injury.

"Working closely with the Advisory Group ensures the Government is getting the best possible expert advice when making this nation-changing scheme a reality," Minister Shorten said.

The Productivity Commission identified the four main causes of catastrophic injury which require a NIIS, namely motor vehicle accidents, medical accidents, workplace accidents, and general accidents occurring in the home or community.

"The only factor which should determine the level of care someone receives is the level of support they require, not the cause of their injury."

The Advisory Group has issued a Communiqué on the outcomes of the meeting, where it endorsed a comprehensive system of lifetime care and support for all the four main causes of catastrophic injury.
