Australia’s military said Thursday it would deploy 1,000 troops to Melbourne in an effort to help contain the country’s only significant coronavirus outbreak.

Victoria state has seen a spike in Covid-19 cases, recording almost 150 new infections over the past week as new clusters have emerged in Melbourne, AFP reported. Authorities recorded at least 37 cases on Thursday, the highest national total since mid-April.

Defense Minister Linda Reynolds said that 1,000 troops would be deployed to Victoria in the coming days. Up to 850 Australian Defense Force personnel will help monitor returned international travelers being held in hotel quarantine while about 200 others will provide logistical and medical support to testing facilities.

Military personnel are manning the borders of states that are closed to outside visitors as well as providing planning support to health and emergency management services, including in Victoria.
