They were both dead," flying fox coordinator, Ms Kay, said. "They'd obviously been there since the day before and they'd spent so much time trying to get out. The [mother's] whole face was mangled, the netting was all around the baby. It's pure torture." This year, there are more than 5000 flying foxes in the ACT - some of the highest numbers the territory has had since they began migrating here en masse in about 2003. As trees begin to fruit, locals have sought to protect them from animals.

But an increase in the popularity of cheap, low-grade netting, purchased online, is achieving just the opposite, Ms Peachey said. "It's a real problem with people using the wrong nets, and even if they're the right nets they're not being put on properly. They need to be put on a frame and stretched, or stretched around the tree and tied in tight," she said. Nets should be white rather than black so they were more visible to wildlife and rescuers, Ms Peachey said. Holes should be no bigger than five millimetres - too small for your finger, or anything else, to get through. However, no netting was the best option to protect wildlife. "I say just take the netting off and share [with the animals]," Ms Kay said.

Some Canberrans refused to opt for white, tightly-woven netting because it looked more obvious on trees. But the results of using the opposite could be devastating, particularly when residents tried to free animals themselves. A grey-headed flying fox stuck in tree netting. Anyone who comes into contact with bats should immediately seek medical attention as they can get the Australian bat lyssavirus, which is related to rabies. "It's unreasonable for volunteers to come out to the same place three times because the owner doesn't like the look of [safer] tree netting," Ms Peachey said. "It's dangerous for us, it's dangerous for them, and it's dangerous for the animal."

The ACT government has no regulations about tree netting, including in the 110-page ACT Tree Protection Act 2005. It is understood there are no plans to introduce formal regulations. "I would like to see the product banned but that is almost impossible. We might be able to convince [bricks and mortar retailers] to limit the sale of the nets but how can you police it online?" Ms Kay said.
