The search area for missing NSW racehorse trainer Bindi Cheers has been extended as it continues into a third day.
Cheers disappeared after leaving Hawkesbury races on Sunday at about 2pm.
Her horse truck was found more than 170km away at a service station in the Newcastle suburb of Beresfield.
The search for the popular Taree-based trainer resumed on Tuesday morning with the search area expanded to include the western side of the freeway near the petrol station.
Local police, officers on trail bikes, police rescue, the dog unit, a PolAir helicopter and SES volunteers are scouring the area near where Cheers’ horse truck was found on Sunday.
