NSW Jobs and Tourism Minister Stuart Ayres presented the plan to crisis cabinet,which includes temperature checks upon entry and mandatory face masks.
The 15,000 crowd proposal would be three times larger than the planned cap for outdoor sporting events post lockdown under the NSW COVID-19 road map.
An ATC spokesman said the organisation had been working with the state government and pointed to modelling that suggested the 70 per cent vaccine target would be met before the event.
The spokesman added they will be implementing bubbles for racing industry participants as part of race day,as they have been doing throughout the pandemic.
“The ATC has been working with government for many months on COVID restrictions and has sent modelling across a range of scenarios,” the spokesman said.
“Several different models indicate rates will reach 70 per cent before the race.”
But NSW Treasurer Dominic Perrottet said he wouldn’t feel comfortable green lighting a crowd for the races if the rest of the city was still in lockdown.
