Members of the Australian Defence Force have joined police to carry out COVID-19 compliance checks in St George and Sutherland Shire.
NSW Police released a video and photos of homes being checked at Bangor and Hurstville on Tuesday.
The checks are designed to ensure stay-at-home and self-isolation orders issued by NSW Health are being observed.
NSW Police Commissioner Mick Fuller made a formal request to the federal government last week for 300 members of the Australian Defence Force (ADF) to assist in the ongoing COVID-19 compliance operation.
Commissioner Fuller said the two organisations had forged a close relationship throughout the pandemic.
"The assistance of the ADF has been essential over the past 18 months - particularly during last year's border operation, the ongoing hotel quarantine operation and the assistance provided with logistics support in the Police Operations Centre," he said.
