Racing has been temporarily suspended in the Australian state of Victoria until at least Friday while a participant is tested for Covid-19.
Racing Victoria pulled the plug on Wednesday's Sandown meeting after learning the person had been told by health authorities they were on a same flight on March 12 as someone who has tested positive.
The participant is not now displaying any symptoms.
The jockey is understood to have ridden at Randwick barrier trials on the 12th before jetting back on a Melbourne-bound flight while also taking part in the Golden Slipper meeting last weekend at Rosehill.
Harness racing in NSW has also been shut down after an employee of the Penrith club tested positive after coming into contact with another person outside the industry.
"As the interstate participant travelled in a private charter flight with two other NSW participants and to minimise the risk of participants at today's Warwick Farm meeting being exposed to COVID-19, the remainder of the Warwick Farm meeting has been cancelled".
Racing NSW followed suit with the Warwick Farm meeting abandoned after five races and Hawkesbury on Thursday called off. The meeting at Launceston in Tasmania was over before it even started due to a track issue but racing was suspended due to the COVID-19 test.
Just as what HRV did with the Bendigo card, Racing and Wagering Western Australia (RWWA) made the decision to abandon the Tuesday live program at Gloucester Park.
"As my superiors have said, the health and safety of our riders in paramount".
"As a result of the protocols we've got in place have had to kick in and we've abandoned this afternoon's meeting at Sandown (Hillside) after Race 2 and abandoned tomorrow's meetings at Kilmore and Pakenham". Narromine will go ahead as planned.
Should the participant return a negative finding, RV will seek to resume racing on Friday while Racing NSW will resume racing in Sydney immediately subject to any government restrictions.
