Just as South Australia seems to be getting on top of its hotel quarantine outbreak, a new one is starting in NSW.

Late on Wednesday night, a NSW hotel quarantine worker tested positive for COVID19 - prompting health authorities to put out alerts and start contact tracing.

NSW Health is taking the extra step of asking people who travelled on certain trains to not only get tested immediately but also self-isolate until further advised.

It follows what happened in Victoria - which suffered a massive second wave due to issues with COVID escaping hotel quarantine.

So on today's Coronacast - are we just going to have to get used to this?
