'I'm always going to miss her': Teresa Bradford's children join mourners on Gold Coast

Hundreds of mourners have turned out at a poignant St Valentine's Day funeral for slain Gold Coast mother Teresa Bradford.

Mourners - including Teresa's four children - attended the public service at Allambe Memorial Gardens, to farewell the 40-year-old nursing student who was murdered by her estranged husband.

Dressed largely in purple - Teresa's favourite colour - devastated family and friends made sure Teresa's funeral was about her life, not her death.

Teresa was killed on January 31 at her Pimpama home at the hands of estranged husband David - just weeks after he was granted bail on domestic violence charges.

While the nature of Teresa's death hung heavily over the service, it was hardly mentioned with family and friends instead painting a picture of a woman who did anything for her children and was a generous, compassionate soul.

Teresa's only daughter Emily showed courage beyond her years as she spoke about just how much she will miss her mum.

"Mum was an amazing, kind woman who pushed for the whole world to be happy," she said.

Teresa's eldest son Brock reflected the heartache in the room during his brief eulogy.

"She was more than just my mother, she was my best friend," Brock said.

"I just wish I had more time to say I love her and I'm always going to miss her."

Teresa's friend Kate McCulloch said while her death had brought anger and pain, it should not be what people think about when they think of her.

"You are more than just a statistic, more than just a victim," Ms McCulloch said.

"You are Teresa. A mother, a sister, a daughter, a friend."

Teresa's brother Darren O'Brien admitted Tuesday's service was the "hardest thing" he'd ever had to do as he farewelled his only sister.

He spoke of how Teresa had endured an increasingly desperate domestic situation and how, tragically, a year that promised hope and safety was now marred.

"Teresa will live on through her four beautiful children's and in our hearts," O'Brien said.

"We promise to look after her kids and know she'll be looking down and holding us to that promise."

Teresa's death has sparked a push to overhaul the bail laws that allowed her estranged husband to be released less than two months after he'd viciously assaulted her.

Queensland opposition leader Tim Nicholls introduced a private member's bill to parliament on Tuesday with proposed bail act changes, including a reversal of the onus of proof for bail for domestic violence offenders, as well as a move to attach GPS trackers to repeat offenders.

Premier Annastacia Palaszczuk said the Labor government was continuing to look into bail changes and other measures and said it was important the laws not be rushed.
