 Col Windon made his debut for Australia on their 1946 tour of New Zealand. His brother Keith was in the side (the only player in the squad that had toured New Zealand previously) which was captained by Bill McLean. Col Windon played nine of Australia's twelve matches on tour, and played both test matches against New Zealand. The first test was played in Dunedin, where New Zealand won 31 – 8. Despite the loss, the New Zealand Rugby Almanack described Windon as "the outstanding forward on either side". The second test was a much tighter affair; played at Auckland, New Zealand scored only one try to win 14 – 10, but according to rugby writer Winston McCarthy, it was "only [New Zealand fullback] Bob Scott's boot that prevented them [Australia] from winning".
