Tonga beats the Wallabies 1973
An unknown Tongan Rugby Union Team toured Australia in 1973 to play two tests with the Wallabies of Australia.
The first test, Tonga lost but it was a close score. The second test in Ballymore stadium in Brisbane Queensland proved otherwise. Tonga won the match 16-11 and it went down as one of Australia's worse loss in Rugby history to a small minnow nation like Tonga.
The irony of this was Toutai Kefu's father played in that team and his son will one day play for Australia and win a Rugby Union World Cup for Australia.
