- World champions New Zealand are chasing a record-breaking 18th consecutive win while Australia wants to end their Bledisloe Cup misery in Saturday's Rugby Championship Test in Sydney.
The New Zealanders, following a 36-13 victory over England in their last match, are equal with the 17-Test winning runs of the 1965-69 All Blacks and 1997-98 Springboks.
New Zealand have not lost since going down to England at Twickenham in December 2012.
But the Wallabies are sensing their time has come after 11 years without the Bledisloe Cup.
The New South Wales Waratahs have given Wallaby supporters optimism with their thrilling 33-32 Super rugby final victory over Canterbury Crusaders.
The Australians, under coach Ewen McKenzie, have also won their last seven Tests, including sweeping their three-Test series against France in June.
