At a guess, it will be when we get closer to 70% double vax. Friday's figures for NSW were 77.3% one dose and 44.5% fully vaxxed.
NSW recorded 1,599 new locally acquired cases of COVID-19 in the 24 hours to 8pm last night.

I wouldn't worry too much about that 44.5% number in terms of how long it will take to climb.
Remember that they went hard initially to get first doses done and stretched out second doses in some cases to accomodate that.
That was before the 5.5m extra Pfizer doses that came from Poland, Singapore and the UK, which after TGA clearance are now making their way into the community (of course not all went to NSW though).
Between the time for second shot, the boost in Pfizer that is starting to now kick in and significant stocks of Pfizer and then Moderna arriving by late September and then into October - I think we'll see a big jump in the % of fully vaxxed over the next 4 weeks.
Another thing: I think they are deliberately keeping mum on what and when in terms of restrictions easing to prevent ongoing vax % falling off a cliff. Look at the US and UK - both were ~60% vaxxed when they 'opened' and both have steadily rising numbers of new infections and deaths. ~60% full vaxxed isn't enough. I get the feeling we'll have little carrots dangled to keep the vax rate ticking along and only when we get past 70% fully vaxxed will we see a significant rollback of restrictions with even more to follow if/when we can get to 80% fully vaxxed.
