Dukes vs Kookaburra vs SG: Which Cricket Ball Does Each Country Use?
A detailed comparison of the three main cricket balls — Dukes, Kookaburra and SG — covering which countries use each, how they swing differently, and why the seam matters.
Not all cricket balls are created equal. The leather sphere at the heart of the game comes in three primary variants — Dukes, Kookaburra, and SG — and the choice of ball fundamentally shapes how a Test match plays out. A Dukes ball in English conditions can swing extravagantly for 60 overs; a Kookaburra in Australia becomes as hard as a rock after 30 overs and skids through low. Understanding the differences between these balls helps explain why fast bowling attacks are built differently across continents.
The Dukes Ball — England and the West Indies
Manufactured by British company Dukes, this ball is used in England, Ireland, and the West Indies. The Dukes is hand-stitched with a pronounced, prominent seam that stays harder for longer than its rivals — often remaining useful for swing well into the 50th and 60th over. The six rows of stitching on each seam quarter give it a firmer grip for bowlers. This explains why England conditions favour seamers and swing bowlers: batters in a Dukes-ball Test face both conventional and reverse swing for extended spells. The ball's harder lacquer coating means it retains its shape, allowing Anderson-style late outswing deep into the second and third sessions.
The Kookaburra Ball — Australia, South Africa and New Zealand
The Kookaburra, made in Australia, is the most widely used ball globally — employed in Australia, South Africa, New Zealand, Sri Lanka, Pakistan, Bangladesh, Zimbabwe, and Afghanistan. It has a machine-stitched, lower seam profile that deteriorates more quickly than a Dukes. After roughly 30–40 overs, the Kookaburra goes soft and lacquer-free, making conventional swing very difficult. This is why spinners become increasingly dominant in the second innings in these countries. However, the worn Kookaburra reverse-swings brilliantly when one side is kept polished and the other roughed up, a craft Pakistani fast bowlers — from Imran Khan to Wasim and Waqar to Shoaib Akhtar — mastered to perfection.
The SG Ball — India
India uses the SG (Sanspareils Greenlands) ball, manufactured in Meerut, Uttar Pradesh. The SG has the highest, most prominent seam of the three balls, which makes it ideal for the spinning tracks of the subcontinent. Its seam assists off-spinners and leg-spinners in gripping the surface, and the ball's softer leather ages quicker, deteriorating into an ideal reverse-swing candidate by the 40th over. England and Australia touring India often struggle with the unfamiliarity of SG's seam profile — it behaves differently off the pitch compared to what their batters face at home, creating an additional layer of home advantage for the Indian team.
Frequently asked questions
Why does the cricket ball swing more in England than in Australia?
The answer lies in the combination of the ball used, the atmospheric conditions, and the pitch surface — but the ball itself is the most important factor. England uses the Dukes ball, which has a hand-stitched, raised, six-row seam that stays hard and pronounced for a much longer period than either the Kookaburra or SG. This prominent seam acts as an aerodynamic rudder: as the ball travels through the air, air flows differently over the seam side compared to the smooth side, creating a pressure differential that curves the ball in flight — this is conventional swing. The Dukes ball can produce this conventional swing consistently for 40–60 overs, far longer than the Kookaburra's effective swing window of roughly 10–20 overs. Atmospheric conditions in England compound the effect significantly. Cool, overcast, humid English mornings are famous for being 'seaming conditions' because moisture in the air increases air density, which amplifies the pressure differential the seam creates. The ball moves more under cloud cover — a phenomenon so well-established it has changed cricket tactics for over a century. Australia, by contrast, plays with the Kookaburra ball under intense UV radiation on hard, bouncy pitches at high-altitude venues like Perth's Optus Stadium. The Kookaburra's machine-stitched seam is lower-profile and wears down within 25–35 overs, after which conventional swing becomes negligible. The Australian climate — dry, hot, sunny — also reduces humidity-assisted swing. However, once the Kookaburra deteriorates, the art of reverse swing kicks in: by roughing up one side of the ball while polishing the other, bowlers can make the older ball swing in the opposite direction to conventional movement, requiring completely different technique from batters. Pink balls used in Day-Night Tests add another dimension: the pink Kookaburra is lacquered more heavily to maintain visibility under lights, and this extra lacquer actually helps it swing longer than the white Kookaburra — making evening sessions in Australia and India's Day-Night Tests particularly challenging for batters.
