A MACKAY couple whose son was killed and dumped in the bush faced a nail-biting wait to see if new 'No Body, No Parole' laws pass through State Parliament.

Leanne and Gary Pullen, whose son Timothy Pullen was killed in 2012 and never found, met with Attorney-General Yvette D'Ath and Mackay MP Julieanne Gilbert in Brisbane Wednesday ahead of the debate.

It was a positive discussion, Mrs Pullen said, which left her quietly confident the Bill would pass. The debate in Parliament was due to start at 4pm Wednesday.

"It (the meeting) went really well. We're happy. She (Ms D'Ath) just wanted to let us know what their (Labor's) legislation was going to include, see if we're happy with it,” Mrs Pullen said.

"She wanted to get our point of view and let us know where they're standing.

"Hopefully, it'll be all good news tonight (Wednesday), but maybe tomorrow (Thursday). Not just good news for us, but other families in future who are sadly in a similar situation.

"It'll be a bittersweet victory for us though, considering we had a perpetrator released last week.”

Luke Shayne Kister was released from prison on July 31 after serving 14 months following his conviction for accessory after the fact to manslaughter, linked to his part in dumping Tim Pullen's body.

He's never revealed Tim's final resting place.

Mrs Pullen said recent weeks had been hectic for herself and her husband, as media interest in the new laws gained traction.

Additionally, putting so much time and effort into seeing the new laws pass has taken a toll.

It's a constant reminder of Tim's untimely death and the family's inability to give him a proper funeral.

"The last two weeks have been really tough. Finding out Kister was being released on parole was just heartbreaking when this legislation was so, so close,” Mrs Pullen said. "It's been a sleepless couple of weeks. Lots of talking, writing, meetings. It's been a very productive couple of weeks.

"We want to make sure the law doesn't just cover someone accused of murder, but everyone involved in something like that.”

Mrs Pullen said if Tim is looking down he's probably "very proud” of his family's efforts to say their goodbyes, cheering them on.

Meanwhile, there has been no renewed push by police to search for his body, Mrs Pullen said.

"I went to police and asked if there was any more news and they haven't (had any),” she said.

"But hopefully someone will eventually talk. Someone has to know. This new law has to be some sort of incentive too.”

After lengthy court proceedings, Zane Tray Lincoln, Benjamin Francis Graeme Oakley, Nicholas Voorwinden and Kiera Jeanette McKay were jailed for their involvement in Tim's death. Stephen Dale Renwick was also jailed for accessory after the fact to manslaughter, in relation to the dumping of Tim's body.
