Don Tallon was a key member of Donald Bradman's famous Australian cricket team tour of England in 1948, in which Australia was undefeated in their 34 matches. This unprecedented feat by a touring side earned them the sobriquet The Invincibles. The team's first-choice wicket-keeper ahead of Ron Saggers, Tallon played in four of the five Tests, missing the Fourth Test due to injury. Despite being the preferred gloveman, Tallon conceded byes at a higher rate than Saggers during the tour. Bradman rotated the two glovemen during the tour, and Tallon played in 14 of the 31 first-class matches, taking 29 catches and 14 stumpings. Tallon's catch of Len Hutton in the Fifth Test at The Oval was described as Wisden as the best of the year. He also took a difficult catch to remove George Emmett in the Third Test at Old Trafford, catching a ball that flew to his feet at yorker length. However, Tallon also had some mishaps, with finger injuries inflicted by failing to catch the ball correctly.
