The 2026 T20 World Cup witnessed its biggest upset yet as Sri Lanka defeated defending champions Australia by 8 wickets in a thrilling encounter in Kandy. Chasing a target of 182, Sri Lankan opener Pathum Nissanka played the innings of his life, scoring a magnificent century to guide his team home with 12 balls to spare. 

Australia's innings had started explosively with Mitchell Marsh and Travis Head putting on a century stand, but a dramatic middle-order collapse saw them finish on a sub-par total. Sri Lankan spinners, led by Dushan Hemantha, were instrumental in choking the run flow, taking five wickets during the crucial middle overs on a dry, turning track.

The defeat leaves Australia's World Cup campaign in serious jeopardy, as they now rely on other results to go their way to stand a chance of qualification. Sri Lanka, conversely, has officially secured their spot in the Super Eight stage, marking a triumphant return to form for the island nation on the world stage.
