Vincent O'Dempsey has launched an appeal bid against his convictions for the murders of Barbara McCulkin and her two daughters 43 years ago.

O'Dempsey was last month found guilty by a Brisbane Supreme Court jury of taking Mrs McCulkin, 32, and her daughters Vicki, 13, and Leanne, 11, from their Highgate Hill home on the night of January 16, 1974 and killing them in bushland near Warwick.

A notice of appeal was filed with the courts on Thursday encompassing three counts of murder and one of deprivation of liberty.

In handing down a life sentence in May, Justice Peter Applegarth described O'Dempsey as "beyond redemption" and said he expected him to die in jail.

"You were the principal offender in each brutal killing," Justice Applegarth said.

Garry Dubois, who was found guilty in November 2016 of the children's murder but Mrs McCulkin's manslaughter, is also appealing against his convictions.

Both men protested their innocence at their sentencing hearing on June 1, with O'Dempsey telling the court he was "completely innocent".

"I have never had the slightest reason to harm the three McCulkins in any way, nor did my co-accused," O'Dempsey said.
