The virus is in the wild, not in the sheds.
When two wild birds near Esperance tested positive for H5N1, Papua New Guinea did not wait for the virus to reach a single farm before closing its borders to Australian poultry and eggs. The suspension, issued without warning, strikes at a trade relationship worth over $130 million annually — one built on years of supply chain trust now tested by the ancient tension between precaution and evidence. Australia insists its commercial flocks remain untouched, but in the grammar of quarantine, proximity to danger can carry as much weight as danger itself.
- PNG's quarantine authority moved swiftly and without consultation, banning all Australian poultry and egg imports the moment wild bird detections were confirmed — leaving Canberra flatfooted.
- The economic wound is immediate: PNG absorbs roughly half of Australia's overseas poultry exports, a market that reached a record $133 million last year and cannot easily be replaced overnight.
- Australia's core argument — that commercial farms remain entirely free of the virus and meet World Organisation for Animal Health standards — has so far failed to move PNG officials from their precautionary stance.
- Agriculture Minister Julie Collins has called the ban unnecessary, and federal officials are now in direct talks with Port Moresby, though some shipments are already being turned back with no clear resolution in sight.
- The ripple effects are spreading domestically too, with processor Ingham's locking down its Western Australian plants as a precaution, signalling that the industry is bracing for a disruption that may outlast the initial shock.
Papua New Guinea has suspended all imports of Australian chicken and eggs after two wild birds near Esperance in Western Australia tested positive for H5N1 last week. PNG's National Agriculture and Quarantine Inspection Authority issued the ban effective immediately — a decision that caught Australian authorities off guard, given that the virus has not been detected in any commercial poultry operation.
The stakes are considerable. Australia produced 1.4 million tonnes of chicken meat in the last financial year, and PNG alone absorbs roughly half of what the country exports abroad. Last year's chicken meat exports hit a record $133 million, with eggs and egg products adding a further $15.76 million in an earlier period. For producers who have built their export businesses around these figures, the suspension is a sudden and costly disruption.
What frustrates Australian officials is the gap between the threat and the response. The Department of Agriculture, Fisheries and Forestry has confirmed that Australia's commercial farming systems remain free from high pathogen avian influenza, consistent with international standards. The positive detections involve wild birds only. Agriculture Minister Julie Collins described the ban as unnecessary, stating plainly that Australia's poultry and agricultural production systems remain H5 bird flu-free.
The federal government is now directly engaging PNG to lift the restrictions, though some consignments are already being returned. Meanwhile, processor Ingham's has restricted non-essential access to its Western Australian plants as a precaution, even as its operations remain unaffected by the virus itself.
PNG's decision reflects a logic familiar to quarantine authorities everywhere: when a pathogen as destructive as H5N1 appears anywhere within a trading partner's borders, closing the gate first is the safer instinct. Australia's counter-argument — that wild birds and commercial sheds are meaningfully different — is scientifically sound, but whether it will prove persuasive in Port Moresby, and how quickly, remains an open question. Every day the ban holds, the cost to Australian exporters grows.
Papua New Guinea has shut its doors to Australian chicken and eggs, a move that caught Canberra off guard because the virus hasn't actually made it into the country's farms. Two wild birds near Esperance in Western Australia tested positive for H5N1 last week. That was enough. On Monday, PNG's National Agriculture and Quarantine Inspection Authority issued a suspension on all Australian poultry and egg imports, effective immediately.
The timing stings. Australia produced 1.4 million tonnes of chicken meat in the 2024–25 financial year, and while most of that stays domestic, PNG takes roughly half of what Australia exports overseas. Last year, Australian chicken meat exports hit a record $133 million, with the Pacific and Southeast Asia as the primary markets. Eggs and egg products added another $15.76 million in the 2022–23 financial year. For producers who've built supply chains around these numbers, the suspension is a sudden shock.
What makes PNG's move controversial, at least from Australia's perspective, is the disconnect between the threat and the response. Australian authorities are adamant: the virus has not spread to commercial poultry operations. The Department of Agriculture, Fisheries and Forestry confirmed that Australia remains free from high pathogen avian influenza in its farming systems, consistent with World Organisation for Animal Health standards. Two wild birds tested positive. Other dead birds in South Australia and Western Australia are still being tested. But the farms themselves—the places where Australia's export chickens are raised—remain clean.
Agriculture Minister Julie Collins called the ban unnecessary. "We remain free from H5 bird flu in poultry and agriculture production systems," she said, adding that Australia is actively monitoring wildlife detections and working to reassure trading partners. The federal government is now directly engaging with PNG to lift what it views as an overreaction, though some shipments will have to be sent back.
The suspension also prompted Ingham's, one of Australia's largest chicken processors, to lock down its Western Australian plants this week. Non-essential access was restricted as a precaution, though the company's operations themselves have not been affected by the virus. The Australian Chicken Meat Federation declined to comment on the PNG ban at the time of the announcement, a silence that suggests the industry is still absorbing the blow.
PNG's decision reflects the calculus of quarantine authorities worldwide: when a virus this dangerous appears anywhere in a trading partner's territory, the safest move is to close the gate first and ask questions later. H5N1 is devastating in poultry flocks. But Australia's argument is straightforward—the virus is in the wild, not in the sheds. Whether that distinction matters to PNG's officials, or whether they'll accept Australia's assurances, remains to be seen. The resolution timeline is unclear, and every day the ban holds, Australian exporters lose money.

The Hearth Conversation Another angle on the story
Why would PNG suspend imports if the virus hasn't actually reached Australian farms?
Because bird flu in wild birds near a major poultry-producing region is a red flag. PNG is protecting its own flocks. Once H5N1 gets into a commercial operation, it spreads fast and kills everything. Better to shut the door than risk it.
But Australia says it's still HPAI-free in poultry. Doesn't that count for something?
It does, and that's what Australia's arguing. But PNG's quarantine authority doesn't have to trust Australia's monitoring. They can set their own threshold. Two wild birds is enough for them to say no.
What happens to the chicken that's already been shipped?
Some consignments will be returned. That's money lost, and it creates logistical chaos. Producers don't know if they can sell it elsewhere or if it'll spoil in transit.
Is this about trade politics, or genuine disease control?
Probably both. PNG is being cautious, which is legitimate. But it's also using quarantine rules as a tool. Australia thinks it's overblown. The real question is whether PNG will accept Australia's evidence that the farms are safe, or if this becomes a longer standoff.
What does Ingham's locking down its plants actually accomplish?
It's a signal of seriousness to customers and regulators. It shows they're taking the threat seriously, even if their operations haven't been touched. It's also insurance—if the virus somehow got in, they'd want to say they were already being careful.
How long does this usually take to resolve?
That depends on PNG. If Australia can provide enough testing data and assurances, weeks. If PNG decides to wait and see, it could be months. Every day costs Australian exporters real money.
