The Federal Government will tomorrow release the McCarthy review into the summer live sheep trade to the Middle East.
The review was due to be released today, but was postponed after Cabinet met yesterday.
The ABC understands more details were requested on the scientific advice.
Federal Labor is demanding the immediate release of the report.
The Government called the review after the broadcast of shocking footage of sheep dying and suffering heat stress during voyages to the Middle East last year.
The video prompted widespread demands for an end to the northern summer live export trade to the Middle East.
The live sheep trade is worth $249 million a year.
The review was to advise on stocking density, ventilation, possible air-conditioning, the number and skills of ship crew dealing with animals and the independent observation and reporting of animal welfare.
More to come.
