Two of Australia's leading wool organisations have postponed their merger plans again while they wait for a decision on government support for the integration.

"Analysis of the issues has been more complex and more time consuming than the Minister's staff could have assumed and the proposal remains with the Minister for his decision," said AWS chairman, Barry Walker.

In December, Australian Wool Services (AWS) and Australian Wool Innovation (AWI) said they planned to delay the merger until the end of March while they resolved "a number of outstanding issues."

The two groups said a merger would give manufacturers, retailers and designers a united voice and is an important step for the Australian wool industry.
