Shops and businesses here haven't closed, they are still open much as normal, but they have barriers stopping you from getting too close to the people who work there, hand sanitizer as you go in the door, stickers on the floor showing where you can stand. Some people wearing face masks but only a few.
Restaurants are closed, but most are doing take-away menus.
Pubs and bars are closed.
Movie Theaters are closed.
Schools are closed and are doing on-line learning.
Sporting events that involve crowds are banned.
Public spaces like beaches and parks are supposed to be closed, but you can still see people out and about.
No unnecessary travel.
No more than one person visiting a home if they don't live there. So no family gatherings.
People in some jobs are working from home. Offices are pretty much deserted.
This is what the Australian Government is calling a level 3 lockdown. They got in early and have been over the top with police issuing fines for breaches.
The numbers have been going down, so it's unlikely we will ever go to Level 4 lockdown, but that might change if infection rates start to go up.
Also, we disinfect all groceries and parcels that come into the house. 70% isopropanol mostly, I'm saving the bleach for mixed drinks.
