The International Baseball League of Australia was a baseball league which existed from 1999 to 2002.

The league was created by David Nilsson after he purchased the rights to the Australian Baseball League in 1999 when it was near financial collapse. The International Baseball League lasted for 3 seasons before Nilsson handed the rights back over to the Australian Baseball Federation in 2002. Following the collapse there was no professional baseball league until it was announced in 2009 the formation of the new Australian Baseball League starting in 2010. The idea behind the International Baseball League of Australia was to be a winter league from November to January as a means to help gain off-season competition for players centered in Asia and the United States.^[1]

• In April 1999 Nilcorp officially signed the license of agreement to run a national baseball league in Australia for the next 100 years.
• In December 1999 Nilcorp began the Claxton Shield competition with teams from WA, SA, NSW, Queensland and Victoria.
• In November 2000 the International Baseball League of Australia was formed on the Gold Coast with four teams-the MLB Stars (a team that was made up of USA minor league players), an International team (players from South Korea, United States, Australia, and Japan), Taiwan, and Australia.^[1]

• On 5 December 2000 the Claxton Shield was canceled because due to the poor conditions at the Blacktown Olympic complex. Because of the short notice the International Baseball League was unable to find a replacement venue on such short notice.
• In January 2001 the International Baseball League All-Star game gets canceled.
• In September 2001 the International Baseball League is canceled because of "destabilizing" impact that terrorist attacks on America.
