The government of Australia's premier wine state, South Australia, is to spend A$2m (US$1.55m) on a five year plan to maintain pre-eminence.

SA produces about half the national vintage which last year topped 2m tonnes.

The main objectives of the plan are to promote research and streamline regulations.

Co-chairman of the South Australian Wine Industry Council, Vic Patrick, said the industry was currently pausing for breath after a decade of success and this was a good time for such an initiative.
