As we head into Christmas, many of us are concerned about being named a COVID-19 close contact.
Depending on what state you live and your vaccination status, getting 'pinged' as a close contact may see you isolating for a matter of days or weeks during the holiday period.
To help you keep track of the rules - including the new requirements introduced by NSW - we've rounded up everything you need to know about close contacts where you live.
Here's your handy state by state guide.
New South Wales.
Earlier this week, NSW Premier Dominic Perrottet announced changes to how NSW Health defines a close contact, placing more of a focus on households.
"If you are deemed to be a close contact, it would generally be a member from your household," he said on Wednesday. "[However] there may be occasions where [NSW] Health may determine outside of that definition that you would be a close contact."
He also announced changes to isolation rules, with close contacts no longer required to isolate for seven days.
Instead, if you are deemed a close contact, you will only need to have a PCR test and wait for a negative result before leaving isolation.
That said, if you live in the same household as someone who has COVID-19 or were in a high-risk setting at the time of transmission, you will still need to have a PCR test and isolate for seven days, regardless of the result.

In Victoria, contacts are defined under four categories; household, social, workplace or education.
Household contacts are those who either live with someone with COVID-19 or have spent more than four hours with them in a house, accommodation or care facility. If you a fully vaccinated and named a household contact, you will need to get a PCR test and quarantine at home for seven days. You are also required to get tested again on day six. If it comes back negative, you can leave quarantine on day seven. If you are not fully vaccinated you will need to get a PCR test and quarantine at home for 14 days. On day 13 you need to get tested again and if you receive a negative result, you can leave on day 14.
If you are deemed a social contact then you have spent time with someone (who doesn’t live with you) who has COVID-19. Social contacts are strongly recommended to get a PCR test and isolate until you get a negative result.
Workplace or education contacts are those who were in the same indoor space with another worker who had COVID-19, or if you or your child went to school/childcare with someone who has COVID-19. In these cases, you need to get a PCR test within 24 hours of being notified and isolate immediately until you receive a negative result.
