John Tyson described Ms Rice, his partner of 28 years, as “the perfect mum”, while Jordan was “loving and very protective’.
“I don’t think I can put into words just how much I’ll miss them,” he said.
“The fire in my heart will continue to burn until my time comes to join them.
“God speed, my little angels.”
The funeral of Ms Rice and Jordan was the first to be held since the devastating flash flood roared through the Lockyer Valley last week, killing at least 20 people.
