I'm Ruby Jones and you're listening to 7am.
Chapter 2: What is the current status of bird flu in Australia?
Bird flu has reached Australia, with cases first confirmed in WA and now in South Australia. The strain, detected in three migratory seabirds, is H5N1, a deadly form of the virus that has swept through wild birds overseas, forced farmers to slaughter millions of chickens, spread to mammals and, in the United States, infected dairy cows and farm workers.
Authorities in Australia say the risk to the public is low, but for wildlife, an outbreak could be devastating. Experts fear it could become the tipping point for species already endangered or close to extinction. Today, CEO of the Invasive Species Council, Jack Goff, on the race to stop bird flu becoming a wildlife disaster in Australia. It's Thursday, June 25. Jack, welcome to 7am.
Chapter 3: How serious is the threat of H5N1 to Australian wildlife?
Thanks for coming on the show.
Great to be with you.
So, Jack, yesterday South Australia confirmed our third case of the H5N1 virus. That's after two cases were found in WA. Authorities are trying to work out whether this could spread through Australian wildlife. So, at this point in time, how serious do you think the threat is?
This is a really serious development in Australia. We know that the H5N1 strain of bird flu has been circulating in the northern hemisphere and causing absolute devastation to wildlife wherever it's gone.
Chapter 4: What actions are authorities taking to respond to the bird flu outbreak?
It's also meant hundreds of millions of poultry have either died or had to be slaughtered, and unfortunately it is very virulent and spreads very quickly. So it was always going to probably turn up in Australia, But that theoretical risk is now a real, absolutely real risk.
And whether or not this particular outbreak is contained, we can be sure it will turn up here again, whether it's from migratory seabirds coming from the north of Australia or it's coming up, as this one seems to have, from Australia. Birds that have been in contact with other species in Antarctic waters and particularly from those herd and McDonald Islands.
So this is, you know, worst case scenario for a wildlife massacre. That's really what we're looking at in Australia. Once it takes hold, that's been the experience everywhere around the world.
And the chances are this could be worse in Australia than it has been in the Northern Hemisphere because we haven't had other varieties of high pathogenicity avian influenza circulating before in this country.
Right. So there's not much immunity there in the bird population. Tell me about the response from authorities so far. What happens when these first birds arrive?

Chapter 5: What are the potential impacts of bird flu on endangered species?
What's the response on the ground?
Yeah, so the government should really be praised for the response. And the reason it's been very effective is because there's been two years of really dedicated preparatory work.
We have been getting prepared for this for some time. We are the only continent that is currently free of this H5 bird flu.
We understand that this was initially a great scour found by a vet on a remote southern WA beach near Esperance.
We set it up on the examination bench after we'd put our personal protective gear on to have a look at it. It couldn't stand up. It was trying, but it was very wobbly.
they were very quickly able to determine that this was actually this H5N1 variety of bird flu. Since then, there's been a huge response from governments all around the country. So I've been on calls with hundreds of people from different agencies all around the country, industry groups, as well as environment groups coming together. And that's really unprecedented.
So myself, Minister Watt, Minister Butler and Minister McBain are involved primarily in making sure that right across the federal government, we are coordinating the response at the national level.
This is the first time we've had a large-scale preparatory work for a wildlife disease and that means that Australia really is in the best possible position to slow the spread because just like COVID, the aim here is going to be slowing the spread of this virus so that populations can deal with the impact because we will not be able to eradicate it if it has taken hold.
Right. So you're saying even at this point, containing the virus is unlikely?

Chapter 6: How could the H5N1 virus affect Australia's bird population?
A 90-day national health emergency in Peru and Ecuador as migratory birds from North America bring with them the highly contagious avian or bird flu.
So it spread through the entire South American continent within six months back in 2023 and then skipped over to Antarctica.
A virus that once spread mainly among birds has now crossed into a new environment. And now thousands of seal pups have become victims of a changing disease landscape.
The year before, about a 1% death rate for baby elephant seals went to a 95% death rate. And yet tens of thousands... of dead mammals. We know that overseas it's been in the millions of birds that have been killed in the UK, for example, about a 30% loss of their breeding shorebirds. Terraces of breeding guillemots, puffins,
Chapter 7: What are the risks of bird flu mutating and affecting humans?
Sandwich and roseate turns our rarest breeding species, and the bodies of the dead dot the island wherever you look. And we can expect pretty serious devastation in Australia. We don't know exactly how it will behave. It's been a pretty interesting virus, I guess you could call it, in terms of the way that it behaves in different colonies being quite different.
But devastation seems to be absolutely the name of the game. And fast spreading as well, which means that it's a pretty concerning virus to have here.
And the obvious fear that arises with any kind of serious animal-borne virus is the potential for it to mutate and to become dangerous for other animals and also for humans. So where is the kind of possibility of that?
Yeah, look, at the moment, there's no evidence that this is a serious risk to humans. The government risk assessment is very low for humans. We have seen just under 1,000 cases worldwide, and the death rate for humans who have caught it has been around 50%. So serious when people catch it, but it seems at the moment, people need to have very high levels of contact in order to get the virus.
And in a country like America, where in dairy workers, there's been over 70 cases, much lower death rates than we've seen in, for example, in Southeast Asia with healthcare systems able to respond to it. But Flu viruses are notoriously good at mutating and combining their genes.

Chapter 8: How prepared is Australia for a large-scale bird flu outbreak?
And so one of the things that the government has been saying to people is make sure you go out and get your flu shot because it is actually going to be helpful in reducing the risk of those recombinations of genes in people.
if this disease gets passed on and the message if you do see sick birds is really clear avoid them don't go and disturb them or touch them record it you've got a you know a biosecurity fighting tool in your pocket when it comes to a phone and then make sure that you let the authorities know to the emergency animal diseases hotline still to come is australia ready for an outbreak
Kyllä, se on lempeä kesä nyt, kun elämänmaku on kaikista makein. Mieli kuin nuorena tyttönä kaurapellolla, kun saa liihottaa. Nauti vaan ja ota väli pala välissä. Ai, ai, ai, ai, niin se on. Eloveena.
Täyttä eloa. Jack, you mentioned that the bird population here doesn't have the same immunity as in other places. Can you paint a bit of a picture for me of how this could play out? What a kind of worst case scenario might be for our bird populations?
Yeah, look, when this H5N1 variety starts to spread, it really is going to be a numbers game for our wildlife. And unfortunately, this pressure could be something that tips some of them over the edge on that. One species where there has been some work done studying it has been the black swan, that iconic Australian bird species, which is actually... very abundant.
But unfortunately, in captive black swans overseas, 100% of them died within a few days when they caught this virus. And there seems to be evidence that they don't produce an immune response to the virus. And so it's one of the ones that governments have said, look, could be really under threat, as well as some of the birds that aggregate, like peacocks,
pelicans and ibises that you might not think of as threatened in Australia. And then of course, eagles and falcons and the like, as well as some of our mammals that consume carrion, Tasmanian devils, Australian sea lions that have these other pressures. This really could be one of the things that pushes them over the edge.
And so that's why with BirdLife Australia and the Australian Marine Conservation Society, we've been pushing hard with governments to say biosecurity response is one thing and you're doing that well. But on the other side, we do need a huge scaled up effort that local population or entire species can persist in the face of this threat.
Yeah. I mean, the Australian government would say that it has been preparing for this. It's spent more than $100 million. There's this national task force, there's increased surveillance tools to kind of track the risk. So do you think that there's adequate resources going into the response?
