It is often fatal if left untreated. Many Australian plants have documented therapeutic properties as general antiseptics, inhibiting the growth of a wide variety of bacterial species. This study examines the ability of selected Australian plant extracts to inhibit &lt;em&gt;B. anthracis&lt;/em&gt; growth. &lt;strong&gt;Methods:&lt;/strong&gt; Solvent extracts were prepared using plants with documented ethnobotanical usage to treat bacterial infections, or published antibacterial activity. The extracts were investigated by disc diffusion assay for the ability to inhibit the growth of an environmental strain of &lt;em&gt;B. anthracis&lt;/em&gt;. Their MIC values were determined to quantify and compare their efficacies. Toxicity was determined using the &lt;em&gt;Artemia franciscana&lt;/em&gt; nauplii bioassay.&lt;strong&gt; Results:&lt;/strong&gt; Methanolic and aqueous extracts of &lt;em&gt;Eucalyptus baileyana&lt;/em&gt; and &lt;em&gt;Eucalyptus major&lt;/em&gt; displayed potent antibacterial activity in the disc diffusion assay against &lt;em&gt;B. anthracis&lt;/em&gt;. The methanolic extracts were particularly potent with MIC values as low as 290 &amp;mu;g/mL (&lt;em&gt;E. major &lt;/em&gt;methanolic extract). &lt;em&gt;Tasmannia insipidia&lt;/em&gt; and&lt;em&gt; Tasmannia stipitata&lt;/em&gt; extracts also inhibited &lt;em&gt;B. anthracis &lt;/em&gt;growth, albeit with low efficacy. The &lt;em&gt;E. baileyana&lt;/em&gt; and &lt;em&gt;E. major&lt;/em&gt; methanolic leaf extracts as well as the &lt;em&gt;E. baileyana&lt;/em&gt; aqueous leaf extract induced significant mortality in the &lt;em&gt;Artemia fransiscana&lt;/em&gt; bioassay, with LC&lt;sub&gt;50&lt;/sub&gt; values substantially &amp;lt;1000 &amp;mu;g/mL, indicating the toxicity of these extracts. &lt;strong&gt;Conclusion:&lt;/strong&gt; The potent inhibitory bioactivity of the &lt;em&gt;E. baileyana&lt;/em&gt; and &lt;em&gt;E. major&lt;/em&gt; extracts against &lt;em&gt;B. anthracis&lt;/em&gt; demonstrate their potential as medicinal agents in the treatment and prevention of anthrax. However, their toxicity indicates that their use may be limited to the treatment of the cutaneous form of the disease, or for sterilisation of infected sites.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">6</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">389</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Mitchell Henry Wright&lt;sup&gt;1&lt;/sup&gt;, Anthony Carlson Greene&lt;sup&gt;1&lt;/sup&gt; and Ian Edwin Cock&lt;sup&gt;1,2* &lt;/sup&gt;&lt;/strong&gt;&lt;/p&gt;
