Here's the latest variant picture for Australia.

Detailed genomic sequencing data shared via GISAID shows the BA.1 (Omicron) variant has stabilised at ~92% frequency.

Samples from the state of Victoria have recently been shared, to give a more complete picture.

Here's the latest variant picture for New South Wales, where Omicron superspreader events in mid-December sparked the current wave.

This is my first look at samples shared for January. BA.1 (Omicron) variant is steady at ~92% frequency..

After a delay of a month, samples have finally been shared for Victoria, up to 7 January.

This shows Omicron rose steadily through December and reached 88% frequency.

The issue in Victorian data with samples classified as Lineage = None has continued (shown in grey above).

These are typically 0.1% of most datasets I've looked at. For Victoria, they are in a much higher range: 4-10% frequency.

For Queensland, only 10 samples have been shared after 31 December, but by that point Omicron had reached 90% frequency.

For South Australia, Omicron has recently been in the range of 92-100% frequency.
