New South Wales Health's Dr Vicky Sheppeard says four bats infected with the potentially fatal lyssavirus (LIS-uh-VIRE-us) have already been recorded in the state this year.
When passed to humans, the rabies-like illness can prove fatal if not treated.
People are more likely to come into contact with bats during the birthing season in October and November as young and miscarried pups may be on the ground, prompting people to pick them up or attempt to rescue them.
Dr Sheppeard says people shouldn't touch the bats to avoid the risk of being scratched or bitten and therefore infected.
