NSW Racing Minister Troy Grant has helped launch the new-look Rosehill Racecourse which ahead of the feature spring meeting at the track.
The state government contributed $24 million to the project which has improved spectator access, seating and function capacity.
The upgrade includes a new multi-purpose function space, The Hive, where the bar serves cocktails and food incorporating honey cultivated on the premises.
Australian Turf Club chief executive Darren Pearce said the Rosehill refurbishment was the start of a long-term strategy for racing and entertainment in the heart of Sydney.
"Rosehill Gardens is now one of the best facilities for thoroughbred racing anywhere in the world, and we aim to keep it at the front of the field," Pearce said.
"In future years, along with world-class racing, we want to see Rosehill Gardens play a central role as a major destination for people from across Sydney to enjoy the very best of sport, entertainment and hospitality."
The $1 million Group One Golden Rose will be the feature race at the track on Saturday week.
Grant, who is also the deputy premier, says he hopes other tracks will also be upgraded over the coming years.
"This government is delivering a $235 million boost to the racing industry over the next five years and we will see more upgrades like this to racing tracks across the state," Grant said.
"Thoroughbred racing is booming in NSW and is embodied by our premier racing series The Championships, which has attracted record crowds to country and city meetings.
