The experiment of using Kookaburra cricket balls in some rounds of the County Championship has been scrapped. Kookaburras have been used in some rounds for each of the past three seasons, but the move was largely unpopular due to the trend of bat dominating ball.

Directors of cricket from the 18 first-class counties expressed their desire to end the experiment in October. And the decision was confirmed by a meeting of the England and Wales Cricket Board's professional game committee (PGC) earlier this week.

It means all 14 rounds of the 2026 County Championship season will be played with balls manufactured by Dukes. Dukes are the traditional supplier of cricket balls for first-class cricket played in England. Dukes balls are hand-stitched and, in general, offer more assistance to bowlers.

Kookaburra balls are machine made and are mainly used in countries like Australia, New Zealand and South Africa. The Kookaburra ball was introduced into the County Championship with the idea of preparing English players for overseas conditions. The theory was that it would encourage bowlers of higher pace and lead to spin having an enhanced role.

It was used for two rounds of matches in 2023, and expanded to four rounds for 2024 and 2025. Two rounds of Kookaburra matches earlier this summer, played in June, resulted in a lot of dull cricket. The average first-innings total across the Championship was 430, 59 individual scores of 100 or more were made and Surrey racked up 820-9 declared against Durham at The Oval.

The ECB's high performance arm - those involved in the England teams rather than the county game - still stands by the decision to use the Kookaburra, however, which points to the conflicts within the game. Speaking last month before the decision was confirmed, ECB men's performance director Ed Barney said: "We valued the Kookaburra ball. Has it achieved what we intended to? Yes, 100%. To be most effective with the Kookaburra ball you have to bowl at a higher speed. Has it drawn more spin bowling into the domestic game? Yes it has."

Statistics from the past three County Championship seasons shows the optimal bowling speeds with the Kookaburra were around 85mph, but 75-79mph with the Dukes. Forty per cent of deliveries were bowled by spinners during Kookaburra rounds but only 25% when using the Dukes.

"Ultimately the domestic game has a decision to make of whether it wants its core purpose to be about producing and developing players for international cricket or whether its core purpose is about a product that is competitive and appealing to the domestic context," added Barney. "That is the choice the domestic game and ECB has to make, and it is quite difficult for it to co-exist together."

The move to return to the Dukes for the entire Championship season comes after counties rejected proposals to restructure the competition. A new set-up of 12 teams in the top flight and six in the bottom tier, with each side playing 13 matches, was turned down in favour of the current system.

The Championship will remain with 10 teams in Division One, eight in Division Two, all playing 14 matches.
