BRISBANE, Australia (AFP) - Al-Jazeera journalist Peter Greste arrived home in Australia on Thursday after his release from Egypt where he was detained for more than 400 days, an AFP reporter at Brisbane airport said.

Greste, 49, was to have a private family reunion after disembarking from his flight before walking out to meet supporters and give a brief statement to the media, a family spokeswoman said.

The award-winning correspondent was on Sunday deported to Cyprus from Cairo, where he was being held for allegedly aiding the blacklisted Muslim Brotherhood.

A group of supporters greeted him at the airport with signs saying "Welcome Home Peter" and "Journalism is not a crime" after his plane landed around 00:30am Thursday (10.30pm Singapore time on Wednesday).

Since being released on Sunday, Greste has voiced concern about his Al-Jazeera colleagues still behind bars in Cairo.

He was charged with aiding the blacklisted Muslim Brotherhood movement, along with Al-Jazeera television colleagues Canadian-Egyptian Mohamed Fahmy and Baher Mohamed of Egypt.

Both of Greste's colleagues remain in an Egyptian prison, although Fahmy's family said Tuesday he had renounced his Egyptian citizenship hoping to pave the way for his release.

"Special thanks to all who've supported us over the past year. MUST NOT FORGET THOSE STILL IN PRISON," the Australian reporter wrote in a tweet.

He also posted a picture of himself standing in the sea, giving the victory sign, writing: "Free in Cyprus! Feels sweet. Peter back online for first time in 400+ days."

Australian Prime Minister Tony Abbott said Wednesday he had spoken with Egyptian President Abdel Fattah al-Sisi overnight and thanked him for his efforts to release the journalist.

A statement from the Prime Minister's office said Abbott had "expressed hope that Mr Greste's colleagues Mohamed Fahmy and Baher Mohamed might be released soon".

Greste was due to hold a press conference later Thursday with his mother Lois, father Juris and brothers Andrew and Mike.
