There are 2032 coronavirus cases in NSW, with 114 new cases as of 8pm Monday, but despite the small drop in numbers, authorities are increasingly concerned about community transmission.

In the latest bid to slow the spread of the virus, NSW Health Minister Brad Hazzard signed sweeping new orders late on Monday that could see anyone who leaves their house without a "reasonable excuse" jailed for six months and face a $11,000 fine.
