Hundreds of mourners have attended the funeral service for Hannah Clarke and her three children Aaliyah, Laianah and Trey.

Their remains are being laid to rest in a single white coffin, adorned with pink flowers, with Hannah’s parents Lloyd and Suzanne Clarke surrounded by family, friends and supporters.

Hannah’s younger brother, Nat, told the packed Brisbane church he had loved his “amazing sister” from the moment he was born, and described them not as siblings, but as best friends.

“Hannah was the greatest mum to walk the earth,” he said.

Watch: We lose one woman every week in Australia to domestic violence, but that’s just the tip of a very grim iceberg.

Mr Clarke described his nieces and nephew as beautiful children who reflected their mum.

“Aaliyah, you were everything a big sister should be, brave, strong and quite bossy,” Mr Clarke said.

“Laianah, you were the ratbag, the little middle. There was so much of Hannah in you. You were beautiful, sweet and caring with an amazing imagination. You were the sweetest kid and a beautiful mermaid.

“Trey, mother’s little man and her best surprise.”

Among those paying tribute to the young mum, was friend Lou Farmer.

“Han was the best role model for her daughters; she knew her worth,” Ms Farmer said.

“Hannah, the impact you had on people shows how special you are.”

The funeral comes three weeks after the actions of Hannah’s estranged husband Rowan Baxter sent shock waves across Australia.

The attack that killed Hannah and her children has since sparked calls for greater efforts to bring an end to domestic violence.

On February 19, Hannah was doing her routine school run when her estranged 42-year-old husband doused her car in petrol, burning to death their three children – Lainah, six years old, Aaliyah, four, and Trey, three – and ultimately killing Hannah, who died in hospital a few hours later with burns to 97 per cent of her body.

The killer himself died from self-inflicted wounds.

Friends of Hannah who went to school with her told AAP she had been too scared to leave Baxter, who controlled every part of her life, as she feared he would harm her and the children.

According to her loved ones, Hannah’s death was a final, violent punishment that followed years of non-violent abuse and coercive control.

Prime Minister Scott Morrison, Queensland Premier Annastacia Palaszczuk, Police Commissioner Katarina Carroll, senior police officers, firefighters and paramedics are among those who have gathered in the rain to pay their respects to the family.
