"The first report from the Royal Commission into Victoria's Mental Health System sets the scene for major reform of the state's mental health system", Ms Gillard said.
Mental Health Minister Jim Daly said the phone line will be important to improve universal access to health services.
The confidential 24/7 "Your Mental Health" helpline service has been up and running since October.
"The Government has increased the budget for mental health significantly in recent years; we'll spend just over €1 billion on mental health services next year".
Call teams operating the special phone support service have all received training in SafeTalk.
Taoiseach Leo Varadkar said there are extensive mental health services in Ireland but "it is often the case that they are not well joined up".
"People find it hard to find the right service for them at the right time and in the right place and this is a major attempt to alleviate that and make that better", he said.
"Everything we have heard has confirmed that poor mental health is a pressing yet largely ignored health crisis in Victoria", she said. More information on mental health is also available here.
"We probably talk a little bit less less than we did in the past", he added.
"On being appointed Mental Health Minister over two years ago, I instantly recognised that we had many excellent service providers throughout the country, however it also became apparent pretty quickly that the vast majority of people did not know what the different services providers offered, what was available in their area, or how to get in touch with them", he said. The service information line represents an expansion to our Mental Health services, one of many significant developments and improvements that have occurred within mental health services over the past decade, since the publication of the national mental health policy, A Vision for Change in 2006.
Services such as the Samaritans, bereavement groups and suicide prevention help will be among the support that can be referenced to callers.
The Minister for Health Simon Harris said it will provide "advice, guidance and assistance at a very hard time" for people.
He called for more conversations around the impact of social media and technology.
