Former Sydney Swans AFL player Tony Smith has been granted bail after being charged over his alleged role in the unlawful detention of a bank executive.

Smith handed himself in to police this morning after authorities issued a warrant for his arrest.

He appeared in the Brisbane Magistrates Court charged with one count each of retaliation against a witness, attempting to pervert the course of justice and attempted fraud.

The 48-year-old was granted bail on a $250,000 bond and will be allowed to travel back to Bali, where he works, until his next court appearance later this month.

Last month Clive Palmer's media adviser Andrew Crook and former senior Queensland detective Mick Featherstone were charged in connection with the same incident after raids in Brisbane and on the Gold Coast.

Police allege the trio attempted to coerce the executive into falsifying evidence about a failed multi-million-dollar lawsuit against the National Australia Bank (NAB).

Officers have been investigating claims Crook and Smith lured the witness, an employee of the NAB, to Singapore and on to Batam Island in Indonesia in 2013 using the pretence of a possible job offer from Mr Palmer.

It will be alleged that once on Batam Island, the witness was strip-searched, threatened and forced to make a statement recanting his evidence.

Police said Mr Palmer had no knowledge of, or involvement, in the affair.

On Monday the ABC revealed that Queensland's fraud squad was first told about the alleged kidnap plot two years ago, but failed to act.
