A special envoy from Sweden arrived to North Korea on behalf of the Australian government earlier this week for potential discussions about missing Perth student Alek Sigley.

According to reports by the state-run Korean Central News Agency, Kent Rolf Magnus Harstedt arrived with a delegation at Pyongyang International Airport on Monday, where he met with senior North Korean officials.

Mr Sigley, who had been living and studying in Pyongyang since April 2018, has not been in touch with friends and family for over a week, sparking fears he might have been detained by authorities in North Korea.

During a church service in Canberra ahead of the opening of Federal Parliament, Prime Minister Scott Morrison prayed for the 29-year-old, and confirmed the Coalition was working with the Swedish government on the matter.
