He stayed calm and remembered what he had learnt.
The Lesmurdie Primary School lad said he now wants to be an ambulance driver when he grows up.
His former pre-primary teacher Lorenda Mulligan said Matthew was a credit to himself and his school.
�Something like this is every uplifting and bonding for the school community,� Ms Mulligan said.
�We are so proud of him remembering his safety skills,� she said.
Matthew�s dad Michael was on a farm in Carmel when he spotted a tractor rolling down an embankment towards a dam and the pump shed, which supplies all the water to the property.
Mr Oliver, a physical education teacher and year coordinator at Lesmurdie Primary School, caught up with the tractor.
He tried to jump on but missed his footing and fell backwards.
The tractor rolled between his legs over his pelvis, chest and right shoulder.
Matthew rushed down the hill to find his father still conscious.
He was able to ask his son to run to his car about 500m away, on the other side of the house, to find his phone.
�When Matthew couldn�t find it, he tried to turn on the car so he could push the Bluetooth button to see if that would find the phone but was unable to,� Matthew�s mother Carrie, a schoolteacher at Wattle Grove Primary School, said.
Matthew ran back to tell his dad the bad news before racing off to find someone on the farm to bring back and call an ambulance. Paramedics treated Mr Oliver at the scene before transporting him to hospital.
�Matthew was very calm when I arrived; he didn�t get upset,� Mrs Oliver said.
�He was able to tell me and the police officer exactly what had happened.
�Michael�s injuries were quite miraculous, only a broken pelvis in five places and two broken ribs, no internal damage or organ damage.�
Mr Oliver had an operation four days after the accident on March 21 and had a 10cm screw placed in one of the breaks in his pelvis.
Only 20 days later and he was strong enough to climb into a wheelchair.
He is now recovering at home in Lesmurdie and getting around with the help of crutches.
Matthew�s mother attributed her son�s calm handling of the situation to knowing what to do.
�We had talked about what to do in an emergency and he remembers what he learnt at school,� Mrs Oliver said.
