Ivermectin is a prescription-only drug that is authorized to treat intestinal worms and scabies, among other parasitic infections, in Australia.  The Therapeutic Goods Administration (TGA) cautions against purchasing it from unregulated internet sources because of the possibility of unsafe or counterfeit goods, and it is illegal to buy it over-the-counter.  Health authorities strongly discourage the use of ivermectin for treating COVID-19 because it is not approved for this purpose.  Only a doctor's prescription can grant access, guaranteeing safe and suitable use for authorized conditions.  Misuse or self-medication can lead to serious health risks.
