Accused double-murderer Alan Leahy will have his bail application heard in a far north Queensland court on Wednesday.

Earlier this month, State Coroner Michael Barnes committed Leahy to stand trial over the deaths of his wife Julia-Anne Leahy and her friend Vicki Arnold more than 20 years ago.

Leahy, who has been living in Western Australia, handed himself in at Cairns Police Station on Friday afternoon, just in time to meet the coroner's deadline.

Leahy's bail application will be heard in Cairns Supreme Court on Wednesday morning.

Police are not expected to oppose bail, a spokesman told AAP.

The Office of the Director of Public Prosecutions has said it will ultimately be up to the Director of Public Prosecutions to decide whether Leahy stands trial.

"When the brief of evidence is received ... it will be considered and a decision made as to whether it will proceed," the office said in a statement.

The bodies of Julia-Anne Leahy and Vicki Arnold were found in a four-wheel drive in remote bush on the Atherton Tablelands near Cairns on August 9, 1991.

Mr Barnes overturned previous coronial findings that the women died in a murder-suicide.

He was able to commit Leahy to stand trial as the inquest was heard under the Coroners Act 1958, not the 2003 version now in place.

Leahy's lawyer Malcolm Liston has said his client denies any involvement in the deaths.
