The Australian government is to contribute at least $A100 million towards the Commonwealth Games on the Gold Coast in Queensland in 2018.
Prime Minister Tony Abbott made the announcement at a Commonwealth sports breakfast in Sri Lankan capital Colombo on Saturday.
AAP reports he also spoke with British Commonwealth Minister Hugo Swire, who is involved in next year's Glasgow Games.
Mr Abbott said the Games were of "continuing importance" to the Commonwealth and the federal government was "committed to providing comparable support to the Games on the Gold Coast that were provided to the Games in Melbourne in 2006".
"That is in the order of $100 million or so."
AAP reports federal support is expected to include services for security, customs and immigration.
