The victim's daughter, Thalia, said he would do anything for his five children – and on Saturday, that meant giving his life.

"My dad died protecting his son. Like any father would," she told 9News today.

She said Jacka and her brother Jayden were ambushed at the Smithfield Hotel by a group that included Jayden's ex-girlfriend. 

"They were out for my brother. That's all there is to it," Thalia said. 

"[They] tried running my brother over and got him with a baseball bat," she further alleged. 

"Broke his arm in three places."

She said that ambush prompted her father to travel to the Stebonheath Road property where he was shot dead with his own gun.

"I went to the crime scene myself to have it all sink in. But it hasn't sunk in," she said.

"We're all grieving in our own ways that we know how."

Police have arrested two women and a man in connection with the alleged pub attack at the Smithfield Hotel, charging them with affray.

They have not been charged over Troy Jacka's death.

"Revenge is coming. And it's going to happen," Thalia said.

"Either the police do it, or we're going to do it ourselves. It's just how it's going to go."

The investigation into the shooting is ongoing.
