What You'll Learn
Bats are found in Queensland, Victoria, and Tasmania
In Queensland, there are two main types of bats: microbats and megabats. The latter includes flying foxes, which are a well-known species of bat in Australia.
Victoria is home to several species of insectivorous bats, including cave-roosting bats and tree-roosting bats. The Southern Bent-wing bat and the Eastern Bent-wing bat are cave-roosting species that depend on specific maternity caves for raising their young. There are also 21 species of bats in Victoria that roost in tree hollows, some requiring dead trees while others prefer live trees with spouts.
Additionally, buildings in Victoria are sometimes used by insectivorous bats for roosting. These bats do not cause structural damage and can be beneficial in controlling insect populations. It is important to minimise disturbances to bats in overwintering caves, as disturbances can lead to energy depletion and increase their vulnerability to predators.
Tasmania also has a significant bat population, with at least 11 species recorded on the island. The presence of bats in these states highlights their adaptability and diverse habitats across Australia.

They are also found in New Guinea, Indonesia, and India
Bats are found in Australia, New Guinea, Indonesia, and India. The bats of New Guinea are a diverse group, comprising six families, 29 genera, and several endemic species. New Guinea is the world's largest and highest tropical island, and it supports a high percentage of global biodiversity. Its fauna comprises a large number of species of mammals, reptiles, birds, fish, invertebrates, and amphibians.
Indonesia, officially known as the Republic of Indonesia, is a country in Maritime Southeast Asia and southwestern Oceania. While the specific number and variety of bats in Indonesia is unclear, it is known that bats are present in the country.
In India, the Indian flying fox (Pteropus medius), also known as the greater Indian fruit bat, is a species of flying fox native to the Indian subcontinent. It is one of the largest bats in the world, weighing up to 1.6 kg (3.5 lb) with a wingspan of 1.2-1.5 m (3 ft 11 in – 4 ft 11 in). It is of interest as a disease vector, as it is capable of transmitting several viruses to humans. It is nocturnal and feeds mainly on ripe fruits, nectar, and sap.

Flying foxes are found in coastal and urban areas
Flying foxes, also known as megabats, are found in various parts of Australia, particularly in coastal and urban areas. They are the largest bats in the world, weighing up to 1000 grams with a wingspan of 1.7 meters.
In Australia, they are commonly found in the subtropical regions, including the eastern coast stretching from Queensland to Victoria and more recently, South Australia. They are often seen in major cities like Brisbane, Sydney, and Melbourne, as well as in other urban and suburban areas.
One of the most well-known species, the Grey-headed Flying Fox, has a distribution along the east coast of Australia. They are known to share their camps with other flying fox species and can be found in urban areas like Sydney's Royal Botanical Gardens. The Little Red Flying Fox, another species, breeds out of phase with other flying foxes and is found in South-east Queensland.
The presence of flying foxes in urban areas has been a topic of discussion, with some people considering them a nuisance in these spaces. This perception has led to efforts to disperse the bats or promote coexistence, but these attempts have not always been successful. However, it is important to note that the increased urbanisation of flying foxes may be a behavioural response rather than a result of habitat loss.
Overall, flying foxes are an important part of Australia's wildlife, and they play a crucial role as pollinators and seed dispersers.

They are the only known pollinators of some rainforest species
Australia is home to a diverse range of bat species, with around 77 to 81 known species found across the country, including Lord Howe and Christmas Island. These bats play a crucial role in the ecosystem, particularly as pollinators of some rainforest species.
One notable example of an Australian bat species that acts as a pollinator is the common blossom bat (Syconycteris australis). This species is known to be an effective pollinator of the cauliflorous bumpy satinash (Syzygium cormiflorum) in the rainforests of north Queensland. Despite making fewer visits to flowers compared to birds or insects, the common blossom bat has been found to be a superior pollinator of this particular rainforest species.
The Grey-Headed Flying Fox (Pteropus poliocephalus), also known as the Australian grey-headed flying fox, is another important pollinator in Australia. These bats feed on the blossoms of Melaleuca and Eucalyptus trees and are capable of moving between tree stands that are kilometres apart. Their ability to cover large distances makes them efficient pollinators, as they can transfer pollen over extensive areas.
Additionally, the Little Red Flying Fox (Pteropus scapulatus), found in eastern and northern Australia, is a significant pollinator and seed disperser. With a wingspan of around 0.8 meters, this small fruit bat feeds on a variety of fruits, nectar, and pollen. They are known to be important pollinators in a range of habitats, including rainforests, woodlands, and mangrove forests.
The Northern blossom bat (Macroglossus minimus) is yet another Australian bat species that contributes to pollination. These bats are known to pollinate the flowers of mangrove and banana trees. Scientists believe that the flowers of certain plant species have evolved to attract bats specifically due to their ability to carry larger amounts of pollen in their fur compared to other pollinators.
In summary, bats in Australia play a vital ecological role as the only known pollinators of certain rainforest species. Their ability to fly long distances and carry large amounts of pollen makes them highly effective in this role, contributing to the diversity and health of Australia's unique rainforest ecosystems.

Bats can be found entangled in fruit netting in suburban areas
Australia is home to a large number of bat species, with around 77 to 81 different species found across the country. Bats can be found in various habitats, including urban and suburban areas, particularly in states like Queensland and Victoria.
One common issue faced by bats in Australia is entanglement in fruit netting, especially in suburban areas. Fruit tree netting is often used by homeowners to protect their fruit trees from bats and other animals. However, this practice can have detrimental effects on bat populations, particularly the flying fox species.
Bats, especially flying foxes, can easily become entangled in the netting, causing severe injuries or even death. The wide-holed nets with mesh sizes greater than 5mm can entangle bats, leading to broken bones, lacerations, and mouth injuries as they desperately try to escape. This issue is more prevalent during the peak fruit season, which coincides with the bat birthing season, resulting in orphaned baby bats.
To address this problem, some states in Australia, such as Victoria, have implemented regulations regarding the use of netting. These regulations specify the maximum mesh size and strand diameter for fruit netting to ensure the safety of wildlife, including bats. It is recommended that homeowners use wildlife-friendly netting and drape it over the entire tree, securing it at the bottom to prevent bats from getting entangled.
Additionally, it is important for the public to be aware of the correct procedures when encountering an entangled bat. People should refrain from attempting to remove the bat themselves, as this can cause further injury to the animal. Instead, they should contact their local wildlife rescue group, which will send trained rescuers to safely disentangle and assist the bat.
