One person per four square metres will be allowed for indoor dining while one person per two square metres will be allowed in outdoor settings.
Only seated dining and drinking is allowed in hospitality venues.
Home-based activities will be capped at 10 people per household, a decrease from the current restriction of 30 people per household.
"We know this is a difficult time of year to be putting these restrictions in place, we would not be doing it if we weren't concerns about the trajectory of the Omicron variant," Mr Marshalls said.

Mr Marshall also urged people to work from home where possible immediately and to also reduce movement around the state.
"My strong message to everybody in South Australia is to wear a mask, do so in indoors in public areas and do so in your officer environment," Mr Marshall added.
"My strong advice to people is to go and get that vaccination."

Mr Marshall said "well in excess of 80 per cent" of today's infections are the Omicron variant.
"Unfortunately the Omicron trajectory right around the world is very worrying,"
"What we do know is the severity is much lower than delta and other strains the problem with omicron is it is highly transmissible"
There are currently 17 people in hospital with the virus and three people in intensive care.
