Anyone who has been in Victoria since January 27 has been urged to check whether they have been to any exposure sites.

The warning comes as Victoria recorded three new cases on Thursday, taking the Holiday Inn cluster to 11.

“The list of venues has been updated today and further updates may follow, so please keep a careful watch on the website,” NSW Health said in a statement.

“If you have been to any of these locations at the times listed, you are at risk of COVID‑19, so please follow the health advice provided.”

Arrivals are being screened at Sydney Airport.

The department said in many cases people will be required to isolate for 14 days.

Since February 4 anyone arriving to NSW by air has been made to fill out a passenger declaration form, detailing whether they have been to venues of concern.

A staff member at the Holiday Inn in Tullamarine is the latest infection linked to the growing hotel cluster which now stands at 11.

Two cases were revealed earlier on Thursday. They were spouses of staff members.

NSW has gone 25 days without community transmission.

The list of coronavirus exposure sites in Melbourne continues to grow in the wake of more positive cases.

Sunbury Square Shopping Centre was added to the list late on Wednesday after it was visited by someone who was infected with COVID-19 on Friday between 3.40pm and 4.30pm.

Commonwealth Bank and HSBC in Glen Waverley were added to the “Tier 1” hot spot list earlier in the evening, meaning anyone who attended at the days and times listed must isolate for 14 days regardless of their test result.

Health officials said a positive case visited the Commonwealth Bank between 1.30pm and 2.45pm on Tuesday and was at the neighbouring HSBC branch between about 2.15pm and 3.30pm the same day.
