Australian resources and agricultural businesses will get more access into Iran after the Coalition said it plans to reopen a trade office there later this year after meetings with Iranian Foreign Minister Javad Zarif in Canberra on Tuesday. 
However, signalling the government is yet to seal a deal over Iranian asylum seekers who have not been accepted as refugees in Australia, Dr Zarif said Iran would not force its citizens to return home.
The trade office, which closed in 2010, will be within the Australian Embassy in Tehran and help boost export and investment opportunities for business.
"Austrade will provide support to Australian businesses immediately from its office in Dubai, and will establish a permanent presence within the Australian Embassy in Tehran from the second half of 2016," a spokesman for Trade Minister Steven Ciobo said. Trade was about $350 million a year under sanctions, and would only rise after the   January nuclear deal, Mr Ciobo said.
"The recent lifting of sanctions has created opportunities for Australian business in areas we excel: mining equipment, technology and services sectors and the supply of our agricultural commodities such as barley and wheat," Mr Ciobo said.
"Austrade has also identified opportunities for commercial co-operation in the health and medical and education and skills training sectors."
Austrade officials visited Iran in   November after a visit by Foreign Minister Julie Bishop, earlier last year.
The government is keen to do a deal with Iran to take back Iranian asylum seekers who have not been accepted in Australia. After Ms Bishop warned earlier this week that negotiations were in their early stages, Dr Zarif said he would not be forcing Iranians in Australia to go back.
"That would be for Australia to decide. It is within the legal rights of Australia based on its legal obligations to make that decision. It's a decision that Australia has to make.
"Then they will decide whether they want to come back to Iran or whether they do not want to come back to Iran. We cannot force them to come back to Iran," he said.
Ms Bishop said it would be up to the UN Security Council to decide whether to investigate Iran's recent ballistic missile tests and whether they had violated a UN resolution, as the US has suggested and Iran has rejected.
