1
White Spot is back in the waterway.
2
Living on our savings, most of us,
3
there's quite a few that,
4
you know, they're doing nothing.
5
The biosecurity risk is not limited purely to prawn.
6
It is all unprocessed, uncooked seafood that comes into this country.
7
It is going to bite the government.
8
It's not a matter of if,
9
it is purely a matter of when.
10
For well over 100 years,
11
the Clarence River in northern New South Wales has been a source of food and work.
12
Recently that's changed.
13
Trawling for prawns runs deep into the make-up of this community and it's in trouble.
14
It's been a long track for the last three years and not being able to work on the small
15
prawn industry type of prawn.
16
It's to the stage now where we've virtually given up hope.
17
The issue, White Spot is back in the waterway.
18
Glen Dawson is the Clarence River Prawn Committee Chair.
19
He says the people of the region are struggling and doing their best to survive.
20
Living on our savings, most of us.
21
There's a few of us are lucky enough to be able to go and catch mullet and catch other fish.
22
There's quite a few that, yeah, they're doing nothing.
23
And trying to get them onto Centrelink,
24
which we've tried to help them all out in, bloody near impossible.
25
So what is white spot?
26
White spot is a highly contagious disease of crustaceans that can kill farm prawns and other farm crustaceans quickly.
27
While crustaceans can carry white spot and be affected,
28
but population impacts like those seen in farm crustaceans are not known to occur.
29
White spot does not affect people and New South Wales prawns and seafood remain safe to eat.
30
In 2022, white spot was first detected in an enclosed hatchery facility on the Clarence River
31
and then later in 2023 it was detected in local prawn farms.
32
The New South Wales DPI are being cautious.
33
The fishers themselves say there are flaws in the testing.
34
No white spot in the river never ever has been.
35
It's only in the ocean.
36
And we believe the last test in the ocean was caused by the cyclone we had there 12 months ago.
37
That current from Queensland, where the white spot is predominant up there,
38
that current run at over five knots down the east coast.
39
And we believe those problems come from up there.
40
Melissa Walker is the manager for aquatic biosecurity programs at New South Wales Department of Primary Industries and Regional Development.
41
She says it's reasonable to ask why the river is being treated as a hot zone,
42
a place where biosecurity restrictions apply.
43
Being a wild school prawn population that it was detected in later in 2024
44
and then in 2025 outside of Evans and Richmond and the Glarence Rivers in 2025,
45
we were unable to separate those areas between the river and that near offshore area in the oceanic populations.
46
There are no vaccines for white spot,
47
so treating them en masse isn't an option.
48
And the only way of killing the disease is by cooking the prawns.
49
Currently, under the New South Wales Biosecurity White Spot Control Order,
50
the requirements are that prawns must be cooked before they move outside of the zone.
51
This means fishers must cook prawns on their trawlers
52
and farmers at their facilities if they want to sell them beyond the local area.
53
Uncooked or green prawns must stay within the zone for local sale or consumption.
54
If people want to move green prawns to a specific land-based facility outside the zone,
55
they have to apply for a permit and have a strict approved biosecurity plan.
56
The same goes for other crustaceans like crabs or marine worms.
57
The intergenerational fishing that has happened on this beautiful Clarence River up until this year has run four,
58
five generations deep.
59
But with the new restrictions on prawn trawling,
60
they're saying
61
that only about five boats could make a living out of what used to be 40 boats trawling on this river.
62
This river is unlike any other river in Australia.
63
We predominantly catch small prawns here.
64
The Asian market like those small green prawns and also the bait.
65
You know, bait goes Australia wide from this river and we'll no longer be able to do that.
66
So, yeah.
67
Across the border near Queensland's Gold Coast,
68
prawn farms on the Logan River were one of Australia's first white spot hotspots.
69
Detected in late November 2016,
70
the disease infected seven farms along this river.
71
All through to February 2017 and it actually devastated all of the prawn farms here
72
and they were all shut down for over a year while they fallowed and tried to do as much biosecurity as possible.
73
Facing a threat never before seen in Australia,
74
biosecurity departments and local growers were pushed to their limits.
75
The farms acted immediately, sealing their gates and stopping water exchange to prevent further spread.
76
They were soon overwhelmed, not just by the disease,
77
but by the waves of scientists and officials who arrived to investigate.
78
Kim Hooper is the executive officer of the Australian Prawn Farmers Association.
79
She says almost 10 years on, prawn farming has changed.
80
Now here in the Gold Coast area they are operating very successfully.
81
The reason being is that they have put in a lot more biosecurity.
82
They did have biosecurity before
83
but it's very hard to have biosecurity for something you didn't know was here in the first place or had come here.
84
Shannon Moore is the general manager at Gold Coast Tiger Prawns.
85
The farm has been operating for 40 years.
86
And they're big.
87
selling between 600 to 800 tonnes per year has taken a lot of work and investment to recover.
88
We farm with a lot less water,
89
with a lot less risk.
90
We've bought some really expensive equipment to help us filter out
91
the water to make sure things are as safe as we can possibly make it.
92
But that risk is always there for us.
93
It's a risk that if White Spot was to enter our farm again,
94
there's a very good chance that we won't be able to farm on this land ever again,
95
especially not with tiger prawns,
96
which I think would be a massive tragedy.
97
Even with all those checks and balances,
98
Queensland's prawn farmers, like those in New South Wales,
99
have strict rules around selling.
100
Dr Stephen Wesch is the principal scientist with the Animal Biosecurity Team at Biosecurity Queensland.
101
For prawn farmers, they have to first cook their prawns if they want to move them outside of the area,
102
which does create a few issues for the farmers.
103
Obviously there's a loss of access for the green prawns market,
104
but effectively that's the only treatment available.
105
They're free to continue to sell green prawns within the area,
106
but everything needs to be cooked if it's going to be moved outside.
107
I think we still make the best prawns in the world.
108
I really have no question about that effort that we put in,
109
the fact that like best aquaculture practice is one of the global standards that we operate under.
110
Most of the things inside that came from Australian prawn farms
111
because we were known to be doing it the best of anybody in the world.
112
So now the rest of the world has to keep up with us.
113
What's the issue for you at the moment when it comes to White Spot?
114
Well right now I guess we're sitting in a world where the thing
115
that brought White Spot to Australia in the first place is still happening.
116
There's still imported raw prawns coming in every single day.
117
The rules in Queensland aren't just restricted to prawn farmers.
118
Like New South Wales, there are fewer trawlers than there used to be.
119
White spots out there in wild populations,
120
particularly in Moreton Bay, within the control area.
121
So what we have in place there are movement restrictions so
122
that we're not unknowingly spreading the virus outside with that product as it moves around.
123
Another heavy blow for the industry has come from the far north,
124
where there hasn't been an incursion of white spot.
125
One of the country's largest wild prawn providers,
126
Raptors and Sons, has closed operation in Karumba,
127
citing significant price slumps from market oversupply and high operational costs.
128
It's that market oversupply that has the whole of industry concerned.
129
David Bobberman is the executive officer of the Queensland Seafood Industry Association.
130
He says a federal government proposal of relaxation of import rules for raw prawns poses a major problem.
131
Oh, what a disaster.
132
How dare the federal government under free trade agreements tell the Australian public
133
that they're quite open to allowing biosecurity risks to come into this nation.
134
It beggars belief.
135
It is just not acceptable.
136
The community needs to stand up and tell the government that this sort of behaviour is not applicable.
137
We don't import raw pork unless it's going to be processed straight away.
138
He says the risk comes when uninformed consumers take raw seafood to use as bait,
139
inadvertently introducing the biosecurity risk into the broader ecosystem.
140
Australia imports thousands of tonnes of unprocessed seafood every year.
141
The biosecurity risk is not limited purely to prawn.
142
It is all unprocessed, uncooked seafood that comes into this country.
143
It is going to bite the government at some stage.
144
It's not a matter of if,
145
it is purely a matter of when.
146
Kim Hooper is just as angry.
147
The government are currently looking at a compliance-based scheme for three countries that have asked for it.
148
And two of those countries have white spot.
149
The proposed compliance-based scheme means relying on those countries to test for disease before they leave their ports.
150
They'll be randomly tested at the Australian border.
151
Instead of mandatory testing of every container.
152
So when I talk about that country that had 4,500 containers
153
and 20 of them had white spot that they said did not,
154
that is one of the countries that has asked for that relaxed biosecurity coming in.
155
Landline requested an interview with Julie Collins, Australia's Minister for Fisheries.
156
Her office has provided this statement instead.
157
The Australian government will never compromise on biosecurity
158
and there has been no change in import policy for prawns imported into Australia for human consumption.
159
David Bubberman says the solution is clear.
160
Is there anything that those big retailers who are selling imported seafood should be doing?
161
I would like to see them stop retailing it.
162
Quite honestly, we're a country that is surrounded by sea.
163
We have an enormous amount of seaford out there.
164
It's sustainably harvested.
165
It is the highest quality out there.
166
For Glen and people working on the Clarence River,
167
the reality of this situation is evident.
168
I'm getting to the age where I'm ready to retire,
169
but the younger fishermen that have got young families and mortgages, absolutely devastating.
170
You worried about them?
171
Oh very, very much.
172
Yeah.
173
Especially the younger ones.
174
I do get emotional talking about them.
175
Yeah.
176
Thank you.

O que é a Técnica de Shadowing?
Shadowing é uma técnica de aprendizado de idiomas com base científica, originalmente desenvolvida para o treinamento de intérpretes profissionais. O método é simples, mas poderoso: você ouve áudio em inglês nativo e repete imediatamente em voz alta — como uma sombra seguindo o falante com 1-2 segundos de atraso. Pesquisas mostram melhora significativa na precisão da pronúncia, entonação, ritmo, sons conectados, compreensão auditiva e fluência na fala.
