Wonthaggi RSL is a small traditional Sub-Branch, operated by a small dedicated team of veterans and volunteers whose aims are to service the veteran community through operating the Bass Coast Veterans and Dependents Welfare Centre, for Welfare and Pension requirements and also to serve the commemorative needs of the local community.

The Wonthaggi RSL holds a modest collection of memorabilia, photos, documents and books relating to military service, as well as a library of more than 900 reference books covering military history and technology. The building itself has local heritage listing and the sub branch was formed in 1918.
