The Manly Drug Education and Counselling Centre (MDECC) is a non-government organisation. MDECC's underlying philosophy is one of harm minimisation and community development is employed as its approach to service delivery. MDECC is funded by NSW Health through Northern Sydney Central Coast Area Health.

MDECC provides innovative programs for young people, parents and families. These include health promotion, early intervention and counselling/treatment programs.

MDECC also has an extensive range of peer education programs that involve the training of peer educators from various target groups. The peer educators are mobilised within their communities to provide informal education to their friends/peers. All programs aim to enhance mental health and wellbeing and reduce the harms associated with drug and alcohol use.

MDECC is based in Manly on Sydney's Northern Beaches. It is a free and confidential service and is accessible by public transport (bus or ferry).
