Townsville Dad Michael Bell has taken the time to write a letter to his missing son, Kalmin.
Michael begun the letter explaining himself to little Kalmin.
"Even though we haven’t seen each other now for 21 days, Daddy hasn’t stopped fighting. Daddy looks at your picture every day, watches our videos, smiles when he sees your face light up.. and he hasn’t stopped fighting."
He goes on to say how much he is missing his buddy.
"Every time Daddy vacuums the floor, he thinks about you as this was our game, every time he drives the car, Daddy thinks about you as we loved taking drives together, whenever I look at my bike and see your little empty seat – Daddy thinks about you."
"There are others who miss you too. Your sisters, your Nana and Grandad, your nephew, nieces and aunty. We all miss you."
