The South Australian border will open to Greater Sydney on the weekend, if no locally acquired cases are recorded in the next two days.
But visitors will need to be tested on day one, five and 12 of their stay and must isolate until they receive a negative result from their first swab.
Health authorities were waiting for the hotspot area to go 14 days without any recorded cases of community transmission before easing border restrictions.
If no new locally acquired cases are recorded in Greater Sydney, the borders will open to Sydneysiders as of 12.01am on Sunday.
More to come.
