Jason Lees, 40, then threw himself to his death.

Mr Lees, who taught at the exclusive Anglican Church Grammar School in the city was also an international Rugby Sevens referee who worked on the IRB’s glamourous Sevens World Tour.

Queensland police said Mr Lees rode a bicycle onto the footpath across the bridge in the early hours of Monday morning before dropping his son over the safety railings.

Jonathn Hensman, head teacher at the Anglican Grammar School, said Mr Lees, was a “much-loved” teacher.

“The impact this sudden news has had on our community is significant and as we work through our grief we are concerned for our boys whom he taught in the classroom or coached on the sports field,” Mr Hensman told the Port Stephens Examiner.

Police said that Mr Lees’ son was not believed to be the subject of a custody battle at present.
