In the weeks following the Broncos maiden Grand Final over St. George in 1992, Johns travelled with the Broncos to England, where he played at centre in the 1992 World Club Challenge against British champions Wigan at Wigan's famous Central Park, helping Brisbane become the first Australian club to win the match in Britain. A week earlier he was a non-playing reserve in Australia's 10–6 win over Great Britain in the World Cup Final at Wembley Stadium, London in front of a World Record rugby league test crowd of 73,631 fans (Johns was the only Australian selected in the 17 not to get any game time in the final).
