Tough measures are being put into place for peopleignoring COVID-19 directions.
With a police on horseback presence in Murray Bridge, community members are urged to keep checking into the venue that they are entering using the COVID QR code.
A SAPOL spokesperson said the Murray Bridge horseback police presence was just police "probably doing proactive policing."
"We're just policing the area and it's just with the horses today. Same as you would do if you would saw them on motorbikes or pushbikes.
"Nothing to worry about."
With operation 'Trace' in full effect, Police Commissioner Grant Stevens recently said there was a level of complacency regarding COVID-19 check-ins.
"SA Police have taken an educational approach to QR codes, however, we expect that by now members of our community would be well versed on their requirements to check-in."
"We are seeing a level of complacency regarding COVID-19 check-ins and the now is not the time to stop using QR codes. As we start to see more large scale community events and with an increase in interstate and New Zealand travel we need to remember the risk that COVID-19 poses to our community.
"South Australia has done very well so far and although there is no current community transmission of COVID-19 in our state we still need to be vigilant with positive cases in our medi-hotel system."
Businesses can face fines of up to $5,060 if they don't enforce checking in, while people will receive a $1,060 fine if they don't scan the QR codes.
There are up to 1 million QR code check-ins daily. More than 59,800 businesses have an active QR code and more than 1.6 million individuals have used check in system.
