All eight
Australia and England have met in Rugby Union test matches 36 times; Australia have won 21 of these encounters, England have won 14 and there has been one draw. The Wallabies have won the Rugby World cup twice, England has won it once.
Australia has always had wallabies. Wallabies are native to the Australian continent, and have subsequently been introduced from there to other parts of the world.
I believe they have been semi finalists 6 times
Twice - 1987 & 2011.
3 times: in 1987, 1999 and 2011. They have never won.
Three times, all lost: 1987, 1999 and 2011.
England have been in the final 3 times - 1991, 2003 and 2007 Winning it in 2003.
The Rugby World Cup has been held 6 times so far. The first one was held in 1987, and every four years after, so 1991, 1995, 1999, 2003 and 2007.
New Zealand won the very first world cup in 1987. They have won the Tri-Nations Cup the most times out of anyone (10 or 11 times) and have been anounced by the International Rugby Board as the worlds best rugby team.
The Rugby World Cup has been in existence since 1987. So 23 years
850 times
Wallabies are not pets. It is illegal to keep wallabies and kangaroos as pets anywhere in the world - but very few people are aware of this.
