The Greens are promising a $260 million youth mental health package, to fund free counselling for anyone under 25.
They're also promising to fund more community initiatives in the health and education sector, begin a mental health inquiry, and work towards extending the free counselling to adults.
Green Party leader James Shaw said more needed to be done to support people through hard times, so that hard times didn't get worse.
"We need to end the stigma and shame for our young people around emotional wellbeing, encourage people to speak up, and when they do, make sure there is help readily available.
"Every suicide is a tragedy, and we know from overseas evidence that there are things government can do that will make a difference to stop suicides from happening.
