A Tropical North Queensland woman whose husband was murdered more than five years ago finally has the 'No Body No Parole' laws she has been campaigning tirelessly for.

And the efforts of Fiona Splitt, along with Gary and Leanne Pullen were praised by Attorney-General and Justice Minister Yvette D’Ath yesterday after the laws were passed by State Parliament.

Ms Splitt’s husband Bruce Schuler disappeared more than five years ago while prospecting near Palmerville Station, north-west of Cairns. Two people were convicted of his murder in July 2015 but his body has never been found.

The laws were passed with an Australian-first provision to broaden the laws to include anyone convicted of being an accessory after the fact to manslaughter.

The laws will be retrospective and apply to people convicted of: murder; manslaughter; accessory after the fact to murder; accessory after the fact to manslaughter, conspiring to murder; unlawful striking causing death; and misconduct with a corpse. 

Ms Splitt expressed her relief yesterday that the laws had finally been passed after two years of campaigning.

"It has been a long and emotional journey to get to this day," she said.

"This legislation not only acknowledges my family's grief and loss but all loved ones of murder victims, especially when we are unable to lay our loved ones to rest.

"I would like to thank everyone who has supported me through this journey."

Ms D’Ath said the legislation would go some way to providing all-important closure for grieving relatives.

“I would like to thank Queenslanders like Fiona Splitt and Gary and Leanne Pullen who have lost loved ones, yet found the strength to advocate for this important reform,” she said.<strike></strike>
