Here states are largely still easing restrictions, although a mask mandate has been reimposed in Queensland and retained in Victoria.
Each state is in different circumstances. Western Australia still has tight border controls and a COVID-zero approach, most of the rest have or are about to ease border restrictions between other states and are tolerating a certain level of transmission.
Restrictions by state are as follows:

New South Wales has had a significant increase in cases including Omicron, in the last two weeks they've gone from 300 per day to 2200 per day, and hospital numbers are increasing in both states.
Schools are ending/have ended for the year and 5-11 year olds will be eligible for the jab in January. As many clusters are centred around schools and summer holidays run until late January, hopefully that has a meaningful impact on transmission. Of course Omicron is a wildcard there.
Two-dose vaccination rates (of the entire population) range from high 60s % in WA, NT and Queensland to low 80s in the ACT. People have started turning out for boosters in the last week and daily vaccinations have increased, but boosters are only available to those with at least five months since their second dose, and many people had their second doses in August-November, so aren't eligible yet.

For the next week I'll be extra careful because I don't want to have to quarantine over Christmas. My second dose was in early October so I can't get a booster until March.
