In 1954–55 England toured Australia for five Ashes Tests. Davidson started his season well, scoring 30 and 27 not out and taking a total of 5/104 as New South Wales drew with England. His victims included leading batsmen Colin Cowdrey and Bill Edrich. However, Davidson succumbed to injury and missed Australia's only win of the series in the First Test, and upon his return in the Second Test, managed match figures of 2/86 and did not pass twenty in either innings as England levelled the series. He was dropped for the Third Test, but continued to perform strongly in domestic matches, including a sequence of 19 wickets in three matches. This included 4/45 including the wickets of Compton, Bailey and Graveney in a tour match against England, and a match-winning performance against arch-rivals Victoria that sealed a second successive Shield triumph with a resounding nine-wicket win in two days. He tore through the Victorians with 5/36 and 4/50, removing Harvey and Test all rounder Sam Loxton twice. It was his best match bowling figures in his career to date.
