According to Guiness World Records, the highest score in a ‘full’ international rugby union match, as sanctioned by World Rugby, or the International Rugby Football Board (IRFB), as the governing body of rugby union was known at the time, is 164-13. On October 27, 1994, in a Pool 2 match during the Asia Rugby Championship, or the Asian Rugby Football Tournament, as it was known, at the Merdeka Stadium in Kuala Lumpur, Malaysia, Hong Kong ran in 26 tries, 17 of which were converted, against Singapore, who scored a solitary converted try and two penalties.
In so doing, Hong Kong eclipsed the previous scoring records for any qualifying tournament for the Rugby World Cup and for the Asia Rugby Championship. The former was set by Italy during their 108-4 hammering of the Czech Republic in Viadana on May 18, 1994 and the latter by South Korea during their 135-3 shellacking of Malaysia in Seoul on September 23, 1992.
Hong Kong full-back Ashley Billington crossed the try line 10 times, for a total of 50 points, thereby setting two new international records, while fly-half Jamie, who kicked all 17 conversions, set another. Ironically, though, the latter record lasted only until the 1995 Rugby World Cup, for which Hong Kong were trying, unsuccessfully, to qualify. On June 4, 1995, in a Pool C match at the Free State Stadium in Bloemfontein, South Africa, New Zealand routed Japan 145-16, with fly-half Simon Culhane, who was making his debut for the All Blacks, successfully converting all bar one of the 21 tries his team scored, including one of his own.
