Hill made his international test début in May 1993, against Zimbabwe at Bulawayo as part of Wales' 1993 summer tour, a tour held concurrently with the 1993 British Lions tour to New Zealand to which several Welsh internationals were called up to. He started all three tests of the tour; a second match against Zimbabwe in Harare and a match against Namibia, scoring a try in two of the tests. His performance earned him a place in the 1994 Five Nations Championship squad, and he made his tournament début against Ireland as a substitute. Hill continued to make appearances for Wales over the next few years, participating in the 1995 and 1996 Five Nations tournaments as well as the 1995 tour of South Africa and the 1996 tour to Australia. However he was omitted from the Wales squad for the 1995 Rugby World Cup. His final cap was against England in the 1997 Five Nations Championship.
