South Australia will end its COVID-19 lockdown on schedule after reporting no new virus infections.
Premier Steven Marshall says the result is a "huge relief" and will allow the shutdown to end at one minute past midnight on Wednesday.
"So a massive thank you to everybody. We acknowledge how tough this week has been," he said.
"We don't put these restrictions in place lightly, but if we didn't we would be in a very different situation."
When the lockdown lifts, SA will keep a range of heightened restrictions including a general density requirement of one person to every four square metres.
Masks will be required in high-risk settings, such as aged care centres and personal care services, in medical services, on public transport and in all indoor public places, including supermarkets.
The wider use of masks is strongly encouraged, including in workplaces.
All food and drink consumption must be while seated and dancing and singing remain banned.
Family gatherings will be limited to 10 people although weddings and funerals can have up to 50.
Schools will reopen on Wednesday and students will also be required to wear masks.
The new restrictions will remain in place for at least a week with the resumption of competitive sport delayed for a further week.
With no new cases, SA's Modbury cluster of coronavirus cases stands at 19 confirmed infections with 11 of those linked to the Tenafeate Creek winery near One Tree Hill.
It began with an 81-year-old man who recently arrived in Australia from Argentina and was quarantined in Sydney before travelling to Adelaide, where he tested positive.
Genomic testing has confirmed the man became infected while in Sydney, not while he was in Argentina.
