Having passed through the ranks of the Hajduk Split youth academy, Bencun was loaned in the summer of 2011 to the Treća HNL Jug side NK Primorac 1929 and after a great half-season in Primorac, he was subsequently recalled to the Hajduk first team by coach Krasimir Balakov in January 2012. Because of a very big competition in the Hajduk's front line, with the likes of Ante Vukušić and Ivan Vuković who had great season, Bencun was sent on half-year loan again in February, this time to NK Dugopolje in Druga HNL.
