Just days after being freed from an Egyptian prison, Australian journalist Peter Greste says he'd like to return to work as a foreign correspondent.

He says he has no immediate plans other than spending time with his family after his 400 days in a Cairo jail but ultimately wants to return to reporting.

"This has opened up a lot of doors and most of those doors I haven't even begun to look through," he told the ABC's 7.30 Report.

"But at the end of it all I find it hard to imagine that I won't get back on the horse and go out on the road again as a correspondent.

"This is the only thing I really know how to do ... and frankly, I still love it."

The Al Jazeera reporter made a jubilant homecoming in Brisbane yesterday morning following his deportation from Egypt on Sunday and two days resting in Cyprus with his brother, Michael.

At a packed press conference later in the day, he said he'd been humbled by the "frankly overwhelming" support from around the world during his incarceration and following his release.

He has pledged to fight to have his colleagues Mohamed Fahmy and Baher Mohamed also freed from prison.
