QUESTION

Is Australia, Bali or Tasmania in the malaria affected area?

ANSWER

While malaria used to be endemic in parts of Australia (not Tasmania—it is too cold), the country was declared to be free of malaria transmission in 1981. However, several hundred cases are reported in Australia every year, mainly brought back by travellers returning from other regions, such as south-east Asia and Africa.

The tropical northern region of Australia, i.e. Northern Queensland and particularly the Torres Strait area, is climatically very suitable for malaria transmission, and some local outbreaks may occur. Similarly, Bali is climatically very suitable for malaria, and some transmission does occur, though not high levels. For both Bali and northern Australia, it is not usually considered necessary to take anti-malarial medication while visiting the region, but precautions should be taken against getting mosquito bites, as this is how malaria is transmitted. Such precautions include sleeping under an insecticide-treated bednet, wearing long-sleeved clothing in the evenings and at night, and wearing insect repellent on exposed skin.
