The 1991 New Zealand rugby union tour of Australia was the 27th tour... by the New Zealand national rugby union team to Australia.
The tour consisted of two matches: a tour match against Australia B and one Test match against Australia. In 1991, the Bledisloe Cup was contested in a home-and-away format, with one Test held in each country.
New Zealand lost the Test match in Sydney. Later that month, during the 1991 Australia rugby union tour of New Zealand, they won the return Test match to retain the Bledisloe Cup.
