South Australian authorities have announced the lifting of border restrictions with most of Queensland and the Northern Territory, while there is an easing of restrictions on gatherings.
Police Commissioner Grant Stevens said on Friday that following a meeting of the transition committee it was decided to lift border restrictions, effective immediately, to northern and regional Queensland, and all of NT except for the local government area of Katherine.
"We are expecting further advice later on today that I see Katherine being included," Mr Stevens said.
Travellers from 11 local government areas in south-east Queensland, including those from Brisbane, are allowed into South Australia, but have to have three COVID-19 tests and isolate until the first negative test.
The rest of Queensland will have no restrictions.
Mr Stevens also said there would be changes to restrictions on public activities in South Australia, which come into effect as of 12.01am on Saturday.
This includes lifting the limits of home gatherings from 10 to 20 people, while private gatherings outside the home are still capped at 50 people, but stand up drinking is allowed at a density of one person per two square metres.
"Private gatherings are those functions not held not at home and not in a licensed premises, but we are allowing vertical consumption," he said.
Private functions at licensed premises will have a cap of 150 people with vertical consumption, at a density of one person per two square metres.
Licensed function centres can have 150 people with stand up drinking for 50 per cent capacity.
"This is something we think the industry will be happy to receive, but it will be a decision they have to make in terms of whether you have seated consumption and three people per four square meters, or stand up consumption and one person per two square metres," Mr Stevens said.
He said there were no changes to mask or dancing rules.
The state's borders are still closed to New South Wales, Victoria and the ACT, with Mr Stevens noting the level of risk from NSW and Victoria was concerning.
