Mental health service Lifeline is being given a $33.8 million cash injection to boost its 24-hour telephone service.
The funding from the Turnbull government in this year's budget will help the charity answer more calls and support the training of staff.
"Sometimes it's hard to reach out for help but during times of need Australians should know someone will be available to hear their concerns and offer them help," Health Minister Greg Hunt said on Sunday.
Prime Minister Malcolm Turnbull praised the work of the thousands of volunteers who work for the organisation.
"Their love changes and saves lives," he said in a social media video about the announcement.
The government says the funding forms part of $4.2 billion dollars invested into mental health services this year.
