Hannah Baxter was taken to hospital in a critical condition today with “extensive injuries”.
Her husband, former rugby league player Rowan Baxter, and the couple’s three children Laianah, Aaliyah and Trey, all aged under 10, died when their car went up in flames on Raven St in Camp Hill.

It is understood Mr Baxter, a former New Zealand Warriors player, was in a custody battle with Ms Baxter, according to The Courier-Mail.
The pair owned Integr8 gym in Capalaba, a 20-minute drive from the scene this morning.
On Instagram, Ms Baxter describes herself as a “proud mumma” and lists her interests as fitness and healthy eating.
“In love with my 2 little princesses and little prince,” her private profile reads.
Ms Baxter has shared numerous photos of her three young children on Facebook including professional black-and-white baby shoots and pictures of them piled on top of her at the gym.
“My main man,” she said on January 8 this year underneath a photo of her in a bright bikini, holding her son Trey.
In March 2019, one woman commented on a photo of the five Baxters: “Absolutely gorgeous Han, you look stunning, what a good looking family x.”
Just over a year ago, Ms Baxter posted a video of her two daughters – then aged three and five – doing a workout on the rower machines, running, lifting weights and doing handstands.
“These little weapons!” she wrote.
She said Aaliyah’s “biggest idol” was Australian Olympic weightlifter and three-time “Fittest Woman on Earth” Tia-Clair Toomey.
“(Aaliyah) was even late for prep last year watching Tia win the The CrossFit Games (her teacher had no idea what she was talking about),” Ms Baxter wrote.
“Her determination blows me away. Row and I have never once forced them to join in but I guess being surrounded by it every day it’s rubbed off.”
She had also previously posted about entering Australasia’s “Fittest Mum” title and wanting to attend the finals in New Zealand in February last year, with a fundraiser set up by Mr Baxter.
Police were called to the street in Brisbane’s east about 8.30am on Wednesday.
“On arrival, police and emergency services have identified five people that were involved in the fire inside the vehicle. I can confirm that we have three deceased children under the age of 10 in the vehicle,” Detective Inspector Mark Thompson told reporters at the scene.
“We have another deceased adult male who was known to the children, and we also have a victim suffering extensive injuries that are also known to the children and the adult male.”
One resident told The Australian that another witness saw a woman, believed to be Ms Baxter, jump from the burning car and yell, “He’s poured petrol on me.”
He said Ms Baxter was “rolling on the footpath in flames”.
According to Ms Baxter’s Facebook, the couple married in October 2012.
“Happy Anniversary to my partner in crime xo love you always & eternally,” Mr Baxter said in a Facebook post three years later, showing a beaming Ms Baxter in their wedding photos.
That same day in 2015, Ms Baxter shared an image of her husband lifting her into the air, forming a heart with her hands.
“What other way would we want to spend our Wedding Anniversary, than by doing a workout together,” she wrote.
“Some couples buy gifts or go out to dinner … (Rowan) & I train together.”
She finished it with hashtags including #trueloverightthere, #partnerincrime, #soulmate, #bestfriend and #babydaddy.
