The Garrison city of Townsville is emerging as Australia's new Army capital with hundreds of soldiers to be relocated to north Queensland over coming years, while Adelaide becomes the home of advanced land-based, long-range strike capabilities. Defence Minister Richard Marles will unveil the massive Army shake-up on Thursday to make the service more focused on conducting missions in littoral waters close to shorelines in the Pacific, where a future conflict could be fought against an adversary such as China.
