There are however a few factors in NSW that haven't worked well enough this time around.
1) Delta is more infectious so has spread faster than the Northern Beaches outbreak.
2) NSW acted as if it wasn't Delta and didn't lock down hard enough or early enough partly because they were ideologically against lockdowns and presumably were also getting pressure from #scottyfrommarketing
3) compulsory vaccination for front line and other esssential workers hasn't occurred. An unvaccinated limo driver started this outbreak when he caught Delta from a fight crew he transported and then spread it all over the place.
4) what constitutes an essential service means anything can open with masks, distancing and QR code check ins to allow tracing apart from the food and drink sector that is take away only. This has resulted in 14000 close contacts from only a few hundred cases. 2000 alone from a single case at IKEA. We may have the best contact tracing in the world but I'm sure 14,000 cases is more than they can cope with.
5) location has a huge effect. This outbreak has reached SW Sydney where there is a far larger concentration of lower socio-economic groups and migrant ethnic groups. There is more vaccine reluctance and far more densly populated housing there. Compounded by very poor messaging targeted at these areas. Typically government tends to think everyone watches their press briefings and TV news so don't engage with local groups to get their messaging out there.
And all enabled by #scottyfrommarketing's total feck up of vaccine procurement and refusal to set up, or take responsibility for, dedicated quarantine sites. Hotels allowed Alpha to escape but Delta spreads in standard hotels far more easily.
