Wilson was selected to play for Cornwall on seventeen occasions. He was part of the Cornwall team that reached the County Championship final for the first time in 1908, against Durham. The match, contested on 28 March 1908 at
Redruth, Cornwall, was won by Cornwall 17–3. In 1908, the Olympic Games were hosted in London, and it was decided to include rugby in the event. Although several international teams had initially entered the tournament, the Home Nations were unable to decide amongst themselves who should represent the United Kingdom, and France, the previous winners, withdrew. The
Wallabies were then on a tour of the Home Nations, and were the only team left. The RFU asked Cornwall, the day after Australia had beaten them 18–5, to represent the United Kingdom and to provide some opposition to Australia, rather than allow them to win by default. The match was held on 26 October. The previous day, the Cornwall team took the train to London, stopping off at
Plymouth to have lunch and consume alcohol, then continued their festivities on reaching London. On the day of the match, the Cornish team took a tour of the city in the morning, followed by lunch at the Garden Club, at the invitation of the President of the Cornish Rugby Union. The match was played at
White City alongside the outdoor swimming pool. Australia won the game 32–3.
The Times reported "Cornwall completely failed to find their game, their forwards executed a few good rushes but their backs, without exception, were not only too slow but were continually failing in their fielding. One expected better football from the champion county side." The Australian newspaper
The Age remarked: "The Cornwall forwards were good, but their backs were outpaced and beaten by the cleverness of the Australians." but Australia's Dan Carroll was younger aged 16.
