Victoria tightens border measures with SA as officials urge for non-essential travel to be cancelled

Travellers from Adelaide, including the city's hotspot areas, will be required to take a COVID-19 test and quarantine upon arrival into Victoria as the state tightens its border measures.

The Department of Health confirmed today travel advice and border measures had been revised, with all non-essential travel into South Australia advised to not go ahead.

Victorians have been urged to avoid travelling to South Australia as the state's coronavirus outbreak in the city's north continues to grow.

South Australian residents have also been requested to cancel all travel to Victoria unless it is absolutely necessary, as the state goes back into lockdown for at least six days.

New South Wales issued similar advice this morning.

It comes as Victoria recorded its 19th day of zero coronavirus cases and zero deaths.

"We are - like the South Australian government, requesting that all non-essential travel from South Australia into Victoria not go ahead," Victoria's Health Minister Martin Foley said.

Travellers from Adelaide are facing extra screening at Victorian airports, with the state split up into three "zones of risk".

People from the hotspot areas of Adelaide, known as the 'red zone', are required to quarantine upon arrival and take a COVID-19 test.

Similarly, travellers who have been in metropolitan Adelaide are part of the 'amber zone' of risk and must take a COVID-19 test and isolate until they receive their results.

Regional South Australia has been categorised as "low risk", meaning people from regional communities can enter Victoria as normal.

Victoria's Deputy Chief Health Officer Dr Allen Cheng said the South Australia-Victoria border would remain open at this stage.

"We are watching the situation in South Australia very closely."

Dr Cheng said people entering Victoria from South Australia by road will not be stopped.

A total of 91 people have been tested at airports so far - with all results returning negative.

Travellers from Adelaide who arrived in Victoria before the new border measures were announced will still be required to be tested for COVID-19.

"We've obtained lists of passengers. We are in the process of contacting them and asking them to be tested and isolate as we await those results," he said.

The Victorian Government will also roll out "rapid swab testing" facilities for interstate truck drivers from tomorrow.

The saliva test will take no longer than 10 minutes at the South Australia-Victoria border.

Testing sites will be set up at the regional town of Nhill, in the Wimmera region, with others to be "progressively added" to other major routes.

"It's the second busiest freight route in and out of Victoria and it is vital to keep that open so our friends in South Australia can see this through," Mr Foley said.

Three active cases of COVID-19 remain in Victoria.

Mr Foley said the cases had not dropped off as they were elderly people being monitored closely in hospital.

"The good news is they have not been required to be in intensive care at all during that period," he said.

"The medical advice is that we treat them very cautiously before we send them home."

Dr Cheng said Victoria's streak of zero cases was the longest consecutive run since February.

"This is the longest consecutive run of no new cases since February where we didn't have any community transmission at that time," he said.
