Former Wallabies star Toutai Kefu has left hospital along with two family members after they were injured in a violent home invasion in suburban Brisbane.

The 47-year-old suffered critical wounds to his abdomen while trying to defend his family in the early hours of Monday morning.

In a post to Facebook on Wednesday, Mr Kefu said he was out of hospital with adult children Josh and Madi, and was hopeful wife Rachel would join the family tomorrow.

“We just want to say thank you for everyone’s support, we feel very lucky and grateful,” he posted.

A 15-year-old boy has been charged with attempted murder, assault causing grievous bodily harm, break and enter and other offences over his alleged involvement, while a 13-year-old is accused of burglary and wounding.

The 13-year-old has also been charged over an earlier burglary that saw a silver Hyundai SUV stolen from a Forest Lake home.

A second 15-year-old boy is also in custody. He will be charged but he’s currently in hospital with undisclosed injuries that are not considered serious.
