We are fortunate in Australia not to have ticks that have the Borrelia burgdorferi bacteria.
But below is the protocol from https://www.health.nsw.gov.au/Infectious/factsheets/Pages/lyme_disease.aspx for
What to do if bitten by a tick
If you suffer from allergic reactions to ticks, only attempt to remove a tick whilst at a medical facility such as an Emergency Department.
Remove a tick as soon as possible after locating it. This is best done using fine-pointed tweezers to grasp the tick as close to the skin as possible. Gently pull the tick straight out with steady pressure (without twisting). If you have difficulty, seek medical attention.
Do not try to kill the tick with methylated spirits or any other harsh chemicals as this may cause the tick to inject more toxins. If you have a severe infestation by larval stage ticks (often referred to as grass ticks) take a bath for 30 minutes with 1 cup of bicarbonate of soda added to the water to assist with tick removal.
