None of the state of NSW is in 'lockdown'. The Local Government Areas in Sydney in which most of the cases are arising are not in 'lockdown'.
When the areas in Sydney in which most of the cases are arising are actually 'locked down', NSW will move from half-arsed to fully-arsed. The difficulty with going fully-arsed in those areas is that many of the residents are not used to and are not inclined to do what they've been told by the 'authorities'.
The same does not apply to much of the rest of NSW.
