NSW will open up bookings for COVID-19 vaccinations at its new mass vaccination centre at Sydney Olympic Park in Homebush on May 24, two weeks after the centre opens, to allow time to get a booking system up and running.

NSW Premier Gladys Berejiklian announced the new centre, to operate from a commercial building at the venue, which also houses a drive-through testing clinic and a Commonwealth COVID-19 vaccine clinic, last week.
