Black Caviar maintained her unbeaten record with an effortless success in the Group One Hacer Group William Reid Stakes at Moonee Valley in Australia.

Sent off at odds of 1-25, with each of her six rivals 33-1 or longer, Luke Nolen had Peter Moody's star mare settled in third in the early stages as stablemate Karuta Queen set the gallop.

Black Caviar was soon rolling along in second, though, and turning for home the seven-year-old cruised to the front.

She quickly sprinted three lengths clear and was well in control a furlong out, galloping home on a tight rein to spark scenes of delight at the packed Melbourne track as she notched her 24th consecutive win.
