Henjak became the Brisbane Broncos' reserve grade coach in 1994. He was later promoted to assistant coach under
Wayne Bennett. Henjak was vocal about the alcohol culture of young players and their clubs after his nephew
Matt Henjak and teammate
Haig Sare were involved a drunken pub brawl which left Sare with a broken jaw. Henjak was interviewed for the position of head coach at the Broncos in 2009 following Bennett's departure and was selected to take over the coaching reins for the 2009 season after Wayne Bennett left to head up
St. George Illawarra Dragons. Henjak's coaching career began well, with wins in all of his first three matches until the Broncos played against Wayne Bennett's Dragons in round four and lost. At round 7, his team had won all but one of their matches and were at the top of the ladder, having won 86% of their matches so far that season. But in a rollercoaster of a season for the new coach, Brisbane spent rounds 16 to 22 outside the top eight. Another turnaround in form saw the Broncos come within one match of the grand final in what was Henjak's début season. Henjak could not take the Broncos to the 2010 finals, in which the six-time premiers failed to make the finals for the first time in almost two decades. Despite a late season, 10–6 win over eventual premiers
St. George Illawarra at home, losses to the
Sydney Roosters,
Newcastle Knights (both twice),
Parramatta Eels,
New Zealand Warriors and the
Canberra Raiders all proved costly. On Monday 21 February 2011, it was announced by the Brisbane Broncos that Ivan Henjak had been sacked as head coach, and that his assistant coach
Anthony Griffin would be taking over the reins of the club. In 2014, Henjak was coach of the
Sunshine Coast Falcons in the
Queensland Cup, but quit the job after just ten games in charge amidst speculation he would be replaced. ==References==
