NSW Health says anyone who has been in Victoria after 4pm today must follow the same lockdown measures as Victorians.
The Victorian Government announced today new lockdown restrictions for the next seven days following a surge in cases of a highly infectious COVID-19 strain.
NSW Health said anyone who arrives in NSW after 4pm today will have to stay in their homes or place of residence in NSW for seven days, and can only leave to shop for essential items, medical care, caregiving, outdoor exercise, essential work or education.
People subject to the stay-at-home measures in Victoria should not travel to NSW unless permitted to do so.
It comes just a day after NSW Health urged residents to postpone any non-essential travel to Victoria.
Anyone arriving in NSW by air, rail or road from Victoria must complete a travel declaration that confirms they have not attended any of the growing number of venues of concern.
The form is available on the Service NSW website and can be completed in the 24-hour period before entering NSW or on arrival.
NSW Health continues to urge people have been in Victoria since May 12 to check the Victoria Department of Health website to see if they had visited any of the venues of concern.
