In 2001, Corbellari was selected in Italy's squad for the 2001 ICC Trophy in Canada. However, only days before its scheduled start, the Italian Cricket Federation announced that it was withdrawing its team to protest a change in rules that made four Italian squad members (including Corbellari) ineligible, despite them being Italian citizens. At the 2002 European Championship, which was not subject to the same eligibility rules, Corbellari was again one of Italy's leading players. He took 4/33 against the Netherlands, helping his team to a rare win over that side, and also took wickets against Ireland and Scotland. Over the next few years, Corbellari represented Italy in two more editions of the European Championship, and also in their unsuccessful attempt to qualify for the 2007 World Cup. At the 2007 World Cricket League Division Three tournament, which was Italy's debut in the World Cricket League, he featured in all five of his team's matches, taking five wickets with a best of 2/29 against Fiji. Corbellari's final international appearances came at the 2008 WCL Division Four tournament in Tanzania. In four matches, he took six wickets, including 2/24 against Tanzania and 2/27 against Fiji.
