18 new cases and restrictions reintroduced: Gladys Berejiklian's latest press conference.

NSW has recorded 18 news cases of COVID-19 in 24 hours, sparking tougher restrictions ahead of NYE on Thursday. 

Of the new infections, three are mystery cases with no links to known clusters. Nine of the cases are linked to the Avalon cluster and six are related a new Croydon cluster in Greater Sydney, the origin of which remains unknown. 

In light of the new cases, the NSW Premier has announced new restrictions for NYE.

Restrictions reintroduced for Greater Sydney ahead of NYE. 

Gladys Berejiklian has announced new restrictions for Sydney ahead of New Year's Eve celebrations on Thursday night.

Household gatherings are reduced to a maximum of five visitors, including children for all of Greater Sydney, including Wollongong, the Central Coast, the Blue Mountains. 

The restrictions for the northern part of the Northern Beaches remains unchanged, whilst the southern part of the Northern Beaches can now only have a maximum of five visitors, including children, from within their zone. 

Outdoor gatherings are reduced to a maximum of 30 people, down from 50 people. 

These restrictions will come into effect from midnight tonight, Wednesday December 30, and will be in place until further notice. 

NSW will also restrict people in Greater Sydney from visiting aged care facilities until 11.59pm on January 6, when the restrictions will be revised.

Authorities expecting more cases.

Gladys Berejiklian and NSW Chief Health Officer Dr Kerry Chant say they are expecting the Croydon cluster to grow in the coming days. 

"We are expecting that there will be additional cases linked to that cluster just because of the number of close contacts and the close household contact that a number of those contacts had over the period of Christmas and the preceding days," Dr Chant said.
