Malcolm Turnbull warns gas exporters a domestic shortage is 'clearly unacceptable'

Talks between government and producers on Wednesday follow crisis summit, where PM threatened reservation policy if supply could not be guaranteed

Malcolm Turnbull has warned the LNG chiefs it is "clearly unacceptable" to have a shortage of gas on the east coast of Australia ahead of new talks with the industry in Canberra on Wednesday.

The talks follow an emergency meeting in mid-March where the prime minister warned the LNG industry he would use the commonwealth export powers "in the national interest" if the companies did not deliver explicit guarantees of more supply to the domestic market. They will include the chiefs of major companies, Turnbull and three cabinet ministers.
