Schapelle Corby on cusp of flight back to Australia

High-profile Australian drug mule Schapelle Corby is about to make her long-awaited return to Australia, nearly 13 years after she was arrested for possessing cannabis.

There was initially some doubt that she would be cleared for deportation so soon - but Indonesian Justice officials have confirmed that she is all clear to leave the country.

The 39-year-old, who spent nine years in prison before her release in February 2014, will fly to Brisbane on a Virgin flight from Bali at some point on Saturday (local time).

While Kuta police chief Wayan Sumara said Corby wouldn't receive any special treatment, he would deploy about 100 officers to escort her from her villa to the parole office, before heading to the airport, where she will receive her passport.

Corby will fly out from Ngurah Rai International Airport - the same airport she was initially arrested in more than a decade prior.

In 2004, on a flight from Brisbane, authorities in Denpasar found 4.2kg of cannabis in her unlocked boogie board bag. Corby, who was a beauty therapy student on the Gold Coast, has denied from the start she knew about the drugs.

However, under very strict Indonesian laws, Corby was in jail at the notorious Kerobokan prison for nine years before being released on parole in February 2014. While she was let out of prison, her conditions required her to stay in Indonesia until 2017 to finish her sentence.
