The recent Cricket World Cup down under earned co-hosts Australia and New Zealand A$1.1 billion in direct spending.
The figure comes from a report by PricewaterhouseCoopers, which said the tournament generated the equivalent of 8,320 full time jobs in the two countries serving 145,000 visitors.
"This was the biggest event in Australia since the Sydney Olympics in 2000 and it has changed cricket in New Zealand forever," tournament chief executive John Harnden said.
"The cricket World Cup generated two million bed nights which is great for the tourism industries of both countries."
Australian Sports Minister Sussan Ley called it an "outstanding success across all measures".
"This is highlighted by the contribution it has made to the economies of both countries through trade and tourism as well as the unique benefits of sport diplomacy around the world," she added.
