Is there a missing-middle in Australian mental health care?

Despite the widespread use of the term 'missing-middle' for advocacy in Australia, there is a lack of research characterising the epidemiological characteristics of the group. The validity of advocacy predicated on the basis of the 'missing-middle' care-gap should be reconsidered. Research, such as systematic service mapping and health needs assessment, is a necessary foundation for evidence-based mental healthcare policy, planning and implementation. Without such research, vital government funds may be deployed to 'missing-middle' programmes that may not improve Australian public health outcomes.
