Who should read this?
I was disturbed to hear a recent interview on the ABC Country Hour with the Vice President of the Australian Veterinary Association, Mr Barry Smyth (Media article here and full interview Audio here), stating that this is a concern for veterinarians and horse owners in Queensland (extract of interview here).  This apparent ignorance to the potential for Hendra virus to appear anywhere, any time, only strengthened my resolve to raise awareness via this website.

If you live anywhere in the red shaded area of this map, own, live or work with horses (cats, dogs, guinea pigs or pigs) then you should read on.
Adapted from Hall & Richards (2000)
Flying foxes are known to carry the Hendra virus and although they have not yet found the exact mechanism of how it transfers from the bats to horses (or other animals), they are believed to be the only natural 'host' for the virus.

The four species of flying foxes found throughout Australia in these areas are all known to carry the Hendra Virus.  The fact that there has only been one 'recorded' outbreak outside of Queensland (in northern NSW) does not mean they are not happening, merely that they are not being detected, or recorded.  I predict that as soon as there is a case detected and 'recorded' further south, then awareness in other states will be raised and we are likely to see more and more cases 'recorded'. 

For Queensland residents you can find a map of flying fox camps in Queensland on the Department of Environment and Resource Management website at

Residents in other states should visit their respective state body website or contact DEEM if you wish to view maps of colony locations.

Surveys are carried out to update the information, people need to remember that many colonies move regularly and can travel up to 50klms per night to forage for food.

It is vitally important to follow good biosecurity and hygiene practices even if you do not know of flying fox colonies in the area.
