Prior to the first antivenom development in Australia, many of the snake men had a vast array of snakebite remedies they either used for themselves in the case of bites or pedaled to the public. Treatments such as ammonia, strychnine, chlorinated lime, potassium permanganate, suction caps, alcohol, gunpowder, petrol, toad urine, iodide swabs and pig face plant juice were some that were used and sold. The first antivenom produced in Australia was in 1930 for tiger snake bites. Subsequently, in response to public pressure, other antivenoms were produced.
