About us

What we do

Sonder is an inclusive, not-for-profit organisation that has been providing better quality health and support services to the South Australian community since 1993.

We support thousands of people each year with mental health challenges, alcohol & drug use concerns, chronic disease management and employment.

Clients are able to access multiple services to address their needs from a range of centres located across SA.

Over the past 26 years, the organisation has earned a solid reputation for the delivery of high quality, evidence-based clinical psychological therapy services and is now one of the leading providers of mental health services in the state.

Sonder supports children, young people and adults living with mental health concerns to improve their wellbeing and pursue a life with meaning, hope and purpose.

Additionally, Sonder is the lead agency for headspace Adelaide, Edinburgh North, Marion and Onkaparinga.

The headspace Centres act as a one-stop-shop for young people who need help with mental health, physical health, alcohol and other drugs or work and study support.

Sonder is fully accredited under ISO Standard AS/NZS ISO 9001:2015 and the National Standards for Mental Health Services.

Our accreditation status is maintained by an internal Quality, Risk and Safety Committee, which aims to build, maintain and support a culture of continuous quality improvement with a proactive approach to risk management and work health and safety. Learn more

Our history

Our story begins back in 1993, when Sonder was known as the Adelaide Northern Division of General Practice.

As a division of general practice, the organisation’s purpose was to support general practices to enhance the primary health care experience of people living in northern Adelaide, through the provision of program support, practice support education, training and IT support.

In April 2013, a change in Government led to the transition of Divisions of General Practice into what were known as Medical Locals.

The Adelaide Northern Division of General Practice became the Northern Adelaide Medicare Local, and whilst we retained a focus on general practice, the organisation began to broaden its scope to meet unmet community needs through various community health initiatives, such as Closing the Gap.

A further change in Government in 2015 led to the demise of Medicare Locals and the establishment of Primary Health Networks as commissioning agencies.

The Northern Adelaide Medicare Local was successful in its tender to become the Adelaide Primary Health Network, retaining 50% of staff from the Medicare Local. The other 50% of staff were transitioned into a service delivery organisation called the Northern Health Network (NHN).

The NHN found itself in a new space of competitive tender writing, which meant that almost 100% of our program funding was now dependent on grant funding, through agencies such as the Primary Health Networks.

This new funding landscape meant that the NHN was no longer quarantined to servicing only the north, and our dedication to meeting unmet community needs saw our service footprint expand into other regions of Adelaide and country South Australia.

Our rapid expansion meant that our name ‘Northern Health Network’ no longer reflected the service delivery organisation that we had become.

The NHN needed to revitalise itself into an agency that will remain contemporary and relevant for whatever the future will hold. We decided to re-brand into ‘Sonder’, a name with a definition that resonates well with what we represent as an organisation.

Sonder n. the realisation that each random passerby is living a life as vivid and complex as one’s own.

Our social enterprises

A Social Enterprise is a business venture which allows financial and social values to co-exist. It is a business driven by a social purpose that is at the heart of what they do.

Sonder operates social enterprises, such as Solasta and Sonder IT that aim to be financially sustainable while providing social benefits to local communities.

The revenue generated from Solasta and Sonder IT is re-invested back into Sonder. These small surpluses of income enable Sonder to continue to provide innovative services for clients that align with the organisation’s values and social purpose, beyond allocated funding.
