A new, and more contagious, sub-lineage strain of Omicron is expected to become the dominant strain in the territory, health authorities have warned.

The strain is likely to fuel a rise in case numbers within Canberra over the coming weeks but hospitalisations are expected to remain steady.

In addition planning is under way for a winter rise in COVID cases in the ACT, as authorities ensure there is enough bed capacity in the territory's hospitals and testing centres to handle demand.
