Australia's state of New South Wales announced on Tuesday some further precautionary measures to manage the new Omicron strain, Xinhua reported.
International travellers who have been in the eight African countries during the 14 day period before their arrival in the state must enter hotel quarantine for 14 days, irrespective of their vaccination status.
People will only be able to exit isolation at the end of the 72 hour period if they have received a negative result. After exiting isolation, people must complete an additional PCR test on day six after arrival and comply with the NSW Health guidelines.
The state will also increase penalties for non-compliance with the isolation, testing and quarantine requirements from 1,000 Australian dollar (about 711 U.S. dollars) to 5,000 Australian dollar (about 3,556 U.S. dollars) for individuals, and 10,000 Australian dollar (about 7,114 U.S. dollars) for corporations.
All the new rules will take effect from December 1.
The NSW Premier Dominic Perrottet said the measures were a necessary precaution to help keep people safe until more was known about the Omicron variant.
