The New South Wales Coroner has found television newsreader Charmaine Dragun might not have taken her own life if her mental illness was diagnosed differently.

Charmaine Dragun, 29, jumped to her death from The Gap in Sydney's east in 2007.

An inquest heard the Channel 10 newsreader had been treated for depression for 10 years.

But weeks before her death Ms Dragun was withdrawing from the drug Effexor while being introduced to another one, Lexapro.

In delivering his findings deputy state coroner Malcolm MacPherson said she was a talented person with a loving family, but he said she may have not have taken her life if she had been diagnosed and treated for bipolar II disorder.

He said her diagnosis of depression was "almost certainly wrong".

The coroner also said the cross-tapering of drugs may have led to irrational thoughts before she took her own life.

He has recommended that patients on anti depressants be more carefully monitored.

Charmaine Dragun's family hope the findings will help prevent similar deaths.

Her mother Estelle Dragun said her daughter would have wanted to help others with mental illness

"Hopefully the medical profession will read and take in the findings," she said.

"My daughter then has not died in vain."

Mrs Dragun said her daughter was "beautiful bubbly and the most caring and wonderful daughter anyone could have".

Charmaine Dragun's partner Simon Struthers said mental health issues need to be talked about more.

"Even just raising a bit of awareness and starting people talking about it in the community, that is a start," he said.
