The animal rights charity Humane Society International says the Australian tuna industry must accept some responsibility for what it predicts will be rise in the number of deaths of albatross.
Spokesperson Alexia Wellbelove says last week's decision to increase the quota for southern bluefin tuna will result in 500 more albatross deaths a year from long-line fishing in the Southern Ocean.
The birds seek bait on the many hooks.
Most of Australia's tuna fishery does not use long-lines, but Ms Wellbelove says it can not wash its hands of the situation in the global fishery.
"There's 25 (species of) albatross and petrels found in the area where southern bluefin tuna is fished, and 18 of those are threatened with extinction," she said.
"If Australia can not, with other members of the commission, reach decisions which result in better conservation of this animal then Australia is equally responsible for their demise."
The CEO of the Australian Tuna Association, Brian Jeffriess, says there is no by-catch in the Australian industry, but others are not as responsible.
"There is some reason for the concern, and there's no doubt that the international organisations working on tuna and the countries that do long-line need to do a lot better," he said.
Mr Jeffriess says only about two per cent of the Australian fishers use long-lines, and that they are heavily regulated.
