Perth residents Mark Firkin and Jolie King have been named as the Australian couple detained in Iran.

"The UK Government must continue to insist that Nazanin be freed and allowed to return to the UK with her daughter Gabriella, and it should make urgent representations on behalf of the two British-Australian nationals reportedly now also in Evin Prison alongside Nazanin".

The duo were arrested by Iran authorities some ten weeks ago, reportedly for flying a drone without a license.

The families of the couple have since released a statement via The Australian Department of Foreign Affairs saying, "Our families hope to see Mark and Jolie safely home as soon as possible", ABC Australia reported.

Online followers raised concerns after the bloggers did not post for several weeks.

"We have no further comment to make at this stage and ask that the media respects our privacy at this hard time", they told AAP on Thursday.

The Times of London reported the third person was a British-Australian academic who studied at Cambridge University and was working as a lecturer in Australia when she was arrested in Iran almost a year ago.

The charges against all the three Australians remain unclear but 10-year terms are routinely given in Iran for spying charges, the Times reported.

Firkin, an Australian, and King, a British-Australian, left Perth in 2017 as part of a long and ambitious trip to reach the United Kingdom "overland", driving their vehicle - a Toyota Troopcarrier converted into a small mobile home - to the other side of the world.

The Perth couple jailed in Iran over the alleged use of a drone made no bones about wanting to "wander down the road less travelled".

People must not fly drones over people or large crowds, over the city of Tehran, or over sensitive areas.

"They're never issues that are addressed well by offering public commentary on them", he told reporters in Canberra on Thursday.

"I note that in at least one of these cases it's the view being expressed by family members".

DFAT said it was providing consular assistance to the three families involved.

Earlier this week, the Australian government updated its travel advice for Iran to "reconsider your need to travel" and "do not travel" to areas near the border with Iraq and Afghanistan.
