Update: All public places in the northern beaches will now close down. This includes playgrounds, skate parks, aquatic centres and outdoor gyms however childcare centres and schools will remain open.
And news.com.au says Tas has added suburbs to its hotspot list as were visited by the Nus Drver and Band member:
Tasmania has declared Sydney’s northern beaches area a high risk zone along with three other suburbs, curtailing travel from those places as NSW's coronavirus cluster grows.
The Northern Beaches Local Government Area has been declared high risk, meaning anyone who has been there is asked by Tasmanian authorities to self-isolate immediately and get in touch with health officials to schedule a COVID-19 test.
The same goes for three premises in the Sydney suburbs of Kirribilli, Peakhurst and Penrith. The venues are the Kirribilli Club on Monday, December 14 from 12pm to 3pm, Gannons Park, Forest Rangers FC, Little Rangers session in Peakhurst on Friday, December 11 from 4.30pm to 5.30pm, and the Penrith RSL club on Sunday, December 13 from 1pm to 6pm.
