“The toddler was hit by the family 4WD,” police said in a statement on Saturday morning.
“Sadly, despite the efforts of paramedics at the scene, the 17-month-old girl could not be saved.”
Anna’s mum, Jessi, had been driving to pick up her eldest daughter from the bus stop when the tragedy occurred.
“We just didn’t see her come out,” Ms Seagren told Seven News.
“I saw her as soon after I’d made the mistake so I knew she was gone.”
She urged other parents to “slow down, just don’t rush, take that extra minute” and “give them that last cuddle”.
Together with the little girl’s father, Danny Seagren, she said: “She’s going to be so missed.”
Ms Seagren told Seven News: “We’ve told the other kids that she’s an angel now.”
“She’s not going to come home … but we can still talk to her and we love her.
“And that we were lucky to be her parents for those 17 months.”
“She was just a perfect, happy, boisterous, gorgeous girl,” she told The Advertiser.
Her daughter enjoyed swimming lessons, and learned to kick her legs.
Major Crash investigators have been on Friday to the property and are investigating the circumstances surrounding the fatal incident.
