Hospitalisations have risen to 1066, up from 901 in the previous reporting period, with 83 patients in intensive care.
There are five times as many people being treated for Covid-19 in the state's hospitals as there were in mid-December, although the number of people in intensive care has increased at a slower rate.
Premier Dominic Perrottet last week said the health system "remains strong" and the state was in a "very strong position" despite the fast-growing case numbers and increase in hospitalisations because of the Omicron variant outbreak.
