No new local coronavirus cases in NSW yesterday, but one overnight

New South Wales will officially record zero new cases of locally acquired coronavirus today, but a late-night diagnosis will be recorded in tomorrow's figures.

NSW Premier Gladys Berejiklian confirmed the figures at her press conference this morning.

She said the new case was a child who visited a trampoline centre in Sydney's west where an infected child visited on Sunday.

Yesterday a health alert was issued for the Flip Out Prestons Indoor Trampoline Park at Unit B/238 Hoxton Park Road in Prestons after it was visited by a positive case.

That health advice has now been upgraded, with anyone who visited the centre for any length of time between 11am and 2pm now considered a close contact.

They are being directed to get tested for COVID-19 and self-isolate for 14 days regardless of the result.

In addition, anyone who was there after 2pm that day is a casual contact and must monitor for symptoms and get tested immediately if any develop.

There have also been six coronavirus cases detected in returned travellers in hotel quarantine.

It comes as NSW Police revealed they have launched an internal investigation after a constable visited the room of a recently-returned overseas traveller in hotel quarantine last night.
