Cullen said he had ''100per cent confidence'' in Henjak who, along with the players, refused to speak to the media yesterday when they touched down at Brisbane Airport.

''He's safe as bank,'' Cullen said. ''He hates me saying that because of the old adage that once the board says 'you've got my support' then you're gone.

''But if I didn't say something, people would be up me as well.

''I'm a straight shooter and he's got our 100per cent support for not just this year but next year as well.''

Saturday night's humiliating loss in the nation's capital was the worst loss in the club's history.

It's one of Brisbane's darkest periods since it entered the competition in 1988, having lost seven of its last eight games and conceded 307points.

The Broncos are expected to have to win four of their five remaining matches to avoid missing the finals for the first time in 18 years.

Cullen cut a forlorn figure as he sat alone in the Canberra Stadium grandstand watching the Broncos, lacking any steel in defence and insipid in attack in a 10-try demolition.

''I couldn't believe it was unfolding in front of me,'' the Broncos boss remarked.

Cullen said he felt sorry for Henjak, believing he was ''on a hiding to nothing'' when he replaced guru Wayne Bennett as head coach at the start of this season.

A dejected Henjak, contracted to the end of 2010, spoke briefly after arriving home.

He was asked whether he was feeling the heat in the midst of Brisbane's slump.

''You feel the pressure every week in this position but certainly when you're in the rut that we're in and the points that are getting put on us at the moment, it's certainly tough,'' he said. AAP
