Question: what is the required social distancing space in the home

Answer passage (source: Australia):
page_title: Physical distancing for coronavirus (COVID-19)
section_headers: Households
section_content: Australians should check their state or territory government
restrictions to find out
more about the restrictions in place where they live. As states and
territories move through the steps in the 3–step framework for a COVIDSafe
Australia, restrictions will reduce.
If you are allowed to have visitors at home, you still need to maintain 1.5
metres between people from different households. Keeping visitors to a minimum
will help to reduce the spread of the virus throughout the community.
If someone in your household is sick with cold or flu symptoms, you should:

care for the sick person in a single room, if possible
keep the number of carers to a minimum
keep the door to the sick person’s room closed. If possible, keep a window open
wear a surgical mask when you are in the same room as the sick person. The sick person should also wear a mask when other people are in the same room
protect at-risk family members by keeping them away from the sick person. If possible, find them somewhere else to live while the family member is sick
seek medical advice and have them tested for COVID-19

Answer passage (source: Australia):
page_title: Isolation for coronavirus (COVID-19)
section_headers: Living with other people while in isolation
section_content: If you share your home with others, you should limit your contact with them.
Do this by:

staying alone in your own room
using a different bathroom, if possible
avoiding shared areas
wearing a mask when in the same room as others
not being in the same room as other people, especially people at risk of severe disease (this includes elderly people and people with heart, lung, or kidney conditions and diabetes)
practising good hand hygiene and covering coughs and sneezes
not sharing household items
frequently cleaning the house, especially things people touch often, like door handles

Cover coughs and sneezes
Practise good cough and sneeze hygiene:

cover your mouth and nose with a tissue when you cough or sneeze
if you don’t have a tissue, cough or sneeze into your sleeve or elbow
place used tissues in a bin
wash your hands straight away with soap and water for at least 20 seconds or
use an alcohol-based hand sanitiser

Wash your hands regularly
You should wash your hands often with soap and water for at least 20 seconds.
You can use an alcohol-based hand sanitiser if your hands are not visibly
dirty.
Always do this:

before entering an area where there are other people
before touching things used by other people
after using the bathroom
after coughing or sneezing
before putting on, and after removing, gloves and masks.

Wear a mask
Wear a mask when you are:

in the same room as another person, even if they are also in isolation
passing through communal areas
you visit a health care provider

Make sure your mask covers your nose and mouth at all times. Don’t touch your
mask unnecessarily and replace it if it is wet.
Don’t share household items
You should not share items with people in your home if possible, including:

dishes
drinking glasses
cups
cutlery
towels
bedding

After using these items, wash them with soap and water or put them in a
dishwasher or washing machine.

Reviewer feedback on this answer:
Describes the necessary social distance in detail and includes other hygiene tips.
This basically says not to be in the same room with others. It doesn't really address social distancing space as such. It also has a lot of other, non-relevant advice.

Answer passage (source: Australia):
page_title: Isolation for coronavirus (COVID-19)
section_headers: Steps other members of the household and caregivers can take to prevent infection
section_content: You should only share a house with a person with COVID-19 if:

you are providing essential care to that person
you cannot find a different place to live

If you become very unwell and it is a medical emergency call 000.

Reviewer feedback on this answer:
Provides guidance on providing care to someone with COVID-19, but doesn't explicitly specify how much room to leave.
This is about sharing a house with someone who has COVID-19. It doesn't address social distancing spacing.
