Health Minister Brad Hazzard today told a NSW budget estimates hearing the BA2 sub-variant, thought to be more infectious than the BA1 lineage, was becoming the dominant Omicron offshoot.
Hazzard said preliminary data from the University of NSW (UNSW) indicated cases could "more than double" within six weeks.
"It's very preliminary and we need to do a lot more digging ... but we are concerned at this point that BA2 is amongst us and overtaking BA1," he said.
There were 16,288 cases recorded in NSW today, the highest figure since 27 January.
