A NSW Health statement said, following amended public health orders relating to Melbourne residents from outbreak hot spots, every passenger arriving at Sydney Airport and NSW regional airports had been screened and this would continue.
Every passenger arriving by XPT at Central station had also been screened.
"Screening includes temperature testing, checking for visible symptoms and questions about history," the statement said.
"All passengers who arrive have their temperature checked, and are asked questions about both their health, their travel in Victoria, if they are from a Victorian hot spot, and their reasons for travel.
"Any passengers who display any COVID-19 symptoms, no matter how mild, are tested for the virus and directed to self-isolate.
"Any passenger who is identified as coming from a hot spot and does not meet the very strict eligibility for travel are directed to NSW Police officers.
"None of these travellers have yet been identified as positive for COVID-19."
There are 67 COVID-19 cases being treated in NSW hospitals, with one in intensive care.
In NSW, 2,789 people are known to have recovered from COVID-19.
There is a possible case in an 18-year-old male student from Green Point Christian College on the Central Coast. Confirmation of results is in progress.
Anyone feeling unwell - even with the mildest of symptoms - is urged to have a test.
