Ms Richards says the officer who knocked on her door in December 2011 had also been at the scene of the accident where her 69-year-old dad was killed.

The Redland MP says she fully understands how first responders can suffer from post traumatic stress disorder.

"I remember a police officer knocking on my door one Sunday afternoon to come and tell me that my dad had passed away and that he had attended the scene of the accident," Ms Richards told state parliament on Tuesday.

"And I think there could be nothing more traumatic than having to do that, and having to do that repeatedly, and on a regular basis.

"I genuinely can't imagine what that's like for somebody to have to undertake that job on a regular basis."

That's why the Labor MP is supporting proposed state laws, which have bipartisan support, that will make it easier for first responders to claim workers compensation for PTSD.

The laws are set to pass statement parliament this week.

Under the change, police, firefighters, paramedics and other first responders won't need to prove their PTSD is directly linked to one event at work to be able to claim compensation.

Industrial Relations Minister Grace Grace said it was important to support those who responded to catastrophic bushfires, floods, horrific domestic violence incidents and the COVID-19 pandemic.

"Each and every day, our first responders are exposed to traumatic incidents that most of us could never imagine," she told parliament.

"Attending these types of incidents, whether it be one catastrophic event or a gradual build up over many years, takes a toll on our first responders' mental health."

Opposition industrial relations spokesman Jarrod Bleijie supports the proposed laws, but criticised the government for taking credit for the state's workers compensation scheme.

He said the former Newman government was responsible and the Labor government still hadn't managed to reduce the compensation premium rate for small businesses after six years in power.

"They're making out that all the good things happening in the workers' compensation scheme, that are the envy of every other state, have been because of their brilliant ideas. Well we know it's not, it just is not the case," Mr Bleijie told parliament.
