<jats:p>Aboriginal people of Australia possess a rich knowledge on the use of medicinal plants for the treatment of sores, wounds, and skin infections, ailments which impose a high global disease burden and require effective treatments. The antibacterial and antioxidant activities and phytochemical contents of extracts, obtained from eight medicinal plants used by Aboriginal people of New South Wales, Australia, for the treatment of skin related ailments, were assessed to add value to and provide an evidence-base for their traditional uses. Extracts of<jats:italic>Acacia implexa</jats:italic>,<jats:italic>Acacia falcata</jats:italic>,<jats:italic>Cassytha glabella</jats:italic>,<jats:italic>Eucalyptus haemastoma</jats:italic>,<jats:italic>Smilax glyciphylla</jats:italic>,<jats:italic>Sterculia quadrifida</jats:italic>, and<jats:italic>Syncarpia glomulifera</jats:italic>were evaluated. All extracts except that of<jats:italic>S. quadrifida</jats:italic>showed activity against sensitive and multidrug resistant strains of<jats:italic>Staphylococcus aureus</jats:italic>with minimum inhibitory concentration values ranging from 7.81 to 1000 <jats:italic>μ</jats:italic>g/mL. The sap of<jats:italic>E. haemastoma</jats:italic>and bark of<jats:italic>A. implexa</jats:italic>possessed high total phenolic contents (TPC) and strong DPPH radical scavenging abilities. A positive correlation was observed between TPC and free radical scavenging ability. GC-MS analysis of the<jats:italic>n</jats:italic>-hexane extract of<jats:italic>S. glomulifera</jats:italic>identified known antimicrobial compounds. Together, these results support the traditional uses of the examined plants for the treatment of skin related ailments and infections by Aboriginal people of New South Wales, Australia.</jats:p>
