AN active case of COVID-19 has been identified in the Playford Council area, with the state moving to tighter pandemic restrictions as new infections emerge.

SA Health’s online heat map of active coronavirus infections showed one active case in the Playford Council area as of 11am yesterday (Tuesday) morning.

It is one of 12 new infections in the past fortnight, with all the affected people currently in isolation.

The SA Health heat maps only show the usual place of residence of a confirmed case, not where that person is currently isolating.

On Monday, Premier Steven Marshall announced increased restrictions on licenced venues and home gatherings as the state looks to prevent a large second wave of infections.

From midnight last night, licenced venues are only permitted to serve alcohol to seated patrons, with the Premier flagging further restrictions could be on the horizon.

Restrictions on home gatherings have also been tightened, with 10 people now able to attend another home, down from 50.

“We are concerned about community transmission and we are absolutely focused, 100 per cent, on keeping ahead of the game,” Mr Marshall said.

“That’s what we’ve done in South Australia since day one; we’ve stayed ahead of the game in terms of our testing regime, quarantine regime, in terms of our borders and in terms of our education.

“We still have the highest level of compliance in the country and I do thank the people of South Australia for that.”

Along with the latest restrictions, cutting crowds at Adelaide Oval for AFL matches was touted, as well as tighter restrictions on fitness studios.
