Australian Defence Force personnel will be deployed from Townsville to the Solomon Islands today to help quell political unrest.

This follows the deployment of 23 Federal Police members to the capital of Honiara yesterday, in a bid to bolster local law enforcement dealing with riots which have gripped the city since Tuesday.

Federal Member for Herbert and Defence Force veteran Phillip Thompson says the Townsville soldiers based at the airport in the Solomon Islands would only be used as a last resort.
