An international airline crew that flew into Sydney earlier in December has been fined by NSW Police for breaching self-isolation orders.
It comes as NSW Premier Gladys Berejiklian announced that from Tuesday, international airline crews would be subjected to mandatory hotel quarantine for 14 days.
7.30 understands the airline crew that was fined landed in Sydney on a flight repatriating Australians from South America on Saturday, December 5.
A source told 7.30 that a group of airline staff were caught out and about at a variety of different venues in Mascot when they should have been self-isolating in their hotel rooms.
An initial complaint was made about one staff member leaving the hotel, which was not under police guard. After officers investigated the breach, they found another 12 airline crew had also left their accommodation.
In a statement, NSW Police confirmed that 13 people were issued $1000 penalty infringement notices.
It is believed the airline crew has since returned home but it is not known if any staff members tested positive for COVID-19.
NSW Health told 7.30 it could not comment on individual cases.
NSW Police was contacted for comment.
Currently, international airline crews are able to self-isolate upon their arrival in NSW in a home or other accommodation.
Ms Berejiklian announced that from Tuesday there would be two police-operated hotels in Sydney for airline crews to quarantine in.
