Omicron_Covid_Update, page-146

So the 2 cases from Ozzies coming back from one of those identified southern African countries were doubled jabbed. Asymptomatic as reported. Why is NSW still opening up the state given the fact that fully Vax people can still carry the virus? If they are so confident then there isn't a need to keep the 2 travellers from 14 days quarantine. Double jab and asymptomatic, what am I missing?
