Australia's Schapelle Corby may have had a win against the Bali legal system on Friday, but the question on everyone's lips is whether can she come out on top of a television ratings' battle.

When the news broke that Schapelle could be released from prison as early next week, Channel Nine took the unusual step of shifting its heavily promoted telemovie about the convicted drug smuggler from Monday to Sunday night.

The move will result in Schapelle airing directly against Seven's keenly-awaited dramatic miniseries, INXS: Never Tear Us Apart, on the first night of the 2014 ratings survey.

The likely-to-be-controversial TV feature about Shapelle Corby was original slated to air on Monday, February 10, at 8.30pm and has been covered extensively by weekly TV guides.

The decision to bring the movie forward has fueled speculation that Nine has secured interviews with members of the Corby family, which will be "packaged" with the telemovie.

According to Nine, the schedule change is "due to the current events unfolding in Bali", but the spokesperson did not elaborate.

Schapelle was filmed in secrecy last year and is partly based on journalist Eamonn Duff's book, The Sins of The Father.

Krew Boylan plays the one-time beauty school student who was sentenced to 20 years' jail after more than four kilograms of marijuana were found in her boogie board bag while she was entering Bali in 2004.

The show does not purport to state whether Corby is guilty or innocent of the offence.
