The young student, originally from Perth, was studying in North Korea and disappeared last month. Friends and family became alarmed when he stopped responding on social media and other channels.
Mr Morrison sent Australia’s “deepest gratitude” to Sweden for their help in securing Mr Sigley’s release.
“This outcome demonstrates the value of discreet, behind-the-scenes work of officials in resolving complex and sensitive consular cases in close partnership with other governments. I’m sure we all could not be more pleased that we not only know where Alek is, but we know he is safe,” Mr Morrison said.
The NK News, a South Korea-based news outfit with which Mr Sigley has close ties, reported that the 29-year-old is now in China and will travel to Tokyo later today.
Opposition Leader Anthony Albanese joined Mr Morrison in welcoming the announcement.
“This is indeed good news for Alek, his family and indeed good news for our nation,” Mr Albanese said.
More to come.
