Australia says it will send another 200 troops to Afghanistan, to work on reconstruction projects in the south.
The Australian troops will boost a multinational force
The group will be a "mixed security and reconstruction task force", announced Prime Minister John Howard.
The Australian Defence Force troops will be sent in late July for a two-year mission and form part of a Dutch-led team.
The deployment will almost double the Australian military presence in Afghanistan to nearly 500 soldiers.
In January, Australia announced a new deployment of 110 troops to Afghanistan to fight "terrorism".
Two Chinook transport helicopters were also to join the country's 190 special services soldiers who were already deployed in Afghanistan.
