There are 50,000 legal separation is Australia annually. Of these 60%-70% are initiated by women. This initiative is a response to community concern about the high suicide rate, depression, violence and other dysfunctional responses to grief and loss experienced by men. A study of 4000 suicides by Griffith University found that 70% of adult male suicides were caused by relationship breakdowns. Research has also found that separated men have a suicide rate about 6.2 times that of married men, and about 12 times that of separated women.

Men's Line Australia aims to provide support for men experiencing difficulties in their relationships with partners, ex-partners, children and stepchildren. The service provides information about support services in their locality, practical strategies for self-care and facilitates referral to appropriate organisations and programs. It does not provide legal advice to callers. Women and other family members concerned with male relatives or friends are also encouraged to call and talk it over. Calls from anywhere in Australia are at the cost of a local call.

Men's Line Australia is operated by Personal Emergency Services (PES), a non profit community based organisation located in Melbourne. PES currently operates CareRing - Your Crisis Line and Suicide Helpline Victoria. Both paid and volunteer staff will staff the new service.
