Mr Crook, 48, and Gold Coast private investigator Mick Featherstone, aged 51, have been charged with retaliation of a witness, attempting to pervert the course of justice and attempted fraud.
Crook, from New Farm, appeared before the Brisbane Magistrates Court on Friday afternoon followed by Featherstone.
The court was told there were allegedly emails between Crook, Featherstone and a third man, Tony Smith, involved in luring a National Australia Bank employee to an Indonesian Island with a fake job opportunity.
Barefooted and wearing a shirt and shorts, Crook sat in the dock with his arms folded across his chest. He kept his gaze focused on the magistrate, avoiding any glances in a public gallery full of journalists.
His lawyer argued that Crook had no prior convictions and was not a flight risk having owned a business for the past 20 years in Brisbane.
Crook was granted bail with conditions, including that he does not contact any of the co-accused, the witnesses, NAB employee and that he surrender his passport.
Featherstone was also granted bail under similar conditions.
Both men are not to approach within 100 metres of two Southport NAB branches, despite Featherstone's lawyer saying his client banks with NAB.
Police have also issued a warrant for the arrest of a third man believed to be former AFL player Tony Smith who lives in Bali.
The men allegedly lured a National Australia Bank executive to an Indonesian island off the coast of Singapore with the prospect of a high-paid job with mining magnate Clive Palmer.
"It will be alleged the employee willingly attended the island in the belief that they were going to take part in a lucrative job interview," a police statement said.
Police have said Mr Palmer had nothing to do with the elaborate plot and was a victim in that his name was used to entice the NAB staffer.
Police allege Mr Featherstone pretended to be the job interviewer in an attempt to get recorded admissions from the bank employee that he had lied during a 2012 civil matter to protect the bank's interests.
Smith took the NAB to court over $68 million he lost in a building project and shares in failed mortgage broker MFS.
"After failing to obtain any admissions from the bank employee, it will be alleged that a second plan was implemented which saw two Indonesian nationals dress in what appeared to be security-type uniforms enter the room, detain the bank employee and seize his mobile phone, wallet and passport," police say.
