Racing at Newcastle has been called off with the temperature hitting 41 degrees, higher than original estimates.
Senior jockeys and some trainers who had travelled their horses from Sydney met with stewards before the first scheduled race on Saturday and all agreed to abandon the meeting.
A couple of the horses were reported to be in poor condition after the road trip from Sydney.
Original predictions were for temperatures in the mid-30s.
Saturday’s metropolitan meeting was transferred from Rosehill in Sydney’s west to Randwick where conditions were less oppressive.
