No, France have been finalist twice ('85/'99 but never won) and Wales never been past the semis (which this is their second - '85 was the previous time). The only Northern Hemisphere side to ever win was England (who have also been finalist three times '91/'03/'07). Australia is the most successful side been finalists three times and winning twice ('91/'99/'03). New Zealand have been finalist twice ('85/'95) and won once (South Africa have been finalist twice and won twice, by the way '95/'07). So to conclude, the tri-nations, England and France are the only teams to have ever reached the final. Wining years in bold, if you needed telling.
God, I'm such a nerd with the Rugby World Cup.
