Stunning development in court case over Dane Swan nude video

A South Australian woman has been cleared of sharing an explicit video of former AFL star Dane Swan.

Georgia May Gibson was charged in mid-2018 after footage surfaced online allegedly showing the former Collingwood player.

However, a prosecutor told Melbourne Magistrates Court on Thursday he wanted a "full withdrawal" of the matter and for all charges to be dropped.

He did not explain why the charges against the 21-year-old wouldn't go ahead.

Ms Gibson was initially accused of filming an intimate video of Swan and intentionally sharing the footage with another person.

Magistrate Fiona Hayes struck out the charges and told Ms Gibson she was free to leave the court.

The young woman from Meadows in the Adelaide Hills smiled on learning she would be cleared.

In Victoria, it is illegal to share an intimate or sexual image of a person if they don't agree to it.

The short video appears to show Swan kissing a woman who films his naked body.

Swan, 35, is considered one of Collingwood's greatest midfielders, winning a Brownlow Medal in 2011 and a premiership in 2010 in a 258-game AFL career.

The hard-running star retired in 2016 after badly injuring his foot during a round-one clash with Sydney.

He appeared in the Network Ten reality show I'm A Celebrity ... Get Me Out Of Here! in 2017 and was runner-up in the series.
