After spending a year as the sport manager at the Croatian Basketball Federation, in June 2024, Repeša was announced as the head coach for the newly-promoted Trapani Shark of the Italian Lega Basket Serie A.

In 2005 after Croatia's unsuccessful EuroBasket tournament, Neven Spahija resigned from the national team bench and Repeša took the head coach role.

On 9 February 2012, following the unsuccessful 2011 EuroBasket, Repeša took Croatia bench the second time in his coaching career, this time instead of Josip Vranković, leading the team at the 2013 EuroBasket in Slovenia, where Croatia managed to reach the semifinal of that tournament after 18 years; he also led them at the 2014 World Cup in Brazil, after which Repeša parted ways with the Croatian national team.
