'To put it simply, you can't watch your children 24/7, no matter how well you raise them and trust them, this can happen to anyone,' he wrote in Connect, a Catholic school newsletter.
'Most people get to learn from their mistakes, but Marli didn't have that opportunity.'
'She was 18, not a drinker and had no real interest in drugs. We spoke about them often and she knew the risks.'
'We are all at a loss over what's happened, it was one of those stupid things teenagers do and has left us all completely heartbroken.'

Marli planned to take a gap year to travel and work in her father's hair salon after completing her HSC last year.
She wanted to be a nurse and study at the Australian Catholic University.
The last time her father saw her was when he dropped her off at her part-time job at a takeaway restaurant in Mascot over the Australia Day long weekend.
He told her to stay safe as she got out of the car and the last words she told him were: 'I love you'.

The tragedy came as debate raged over whether revellers should be able to test drugs at music festivals in the wake of five deaths in as many months.
Alex Ross-King died at the FOMO festival in Parramatta Park in Sydney on January 12 in what was the fifth fatality at an organised event in NSW since September.
The 19-year-old's grieving parents begged the state government to consider introducing pill testing.
