Jovi's bravery and efforts have been recognised by the Emergency Services Telecommunications Authority - who made him a Triple-0 Hero.

He is one of 12 young Victorians being recognised for their bravery by ESTA.

The Kangaroo Flat boy sprang to action when he saw his neighbour Rod collapse while mowing the lawn.

"Basically, I saw my neighbour outside on the ground and went across the road to check if he was alright," Jovi said.

"I knocked on his door to see if anyone was home and they weren't so I called the ambulance and told them everything that was wrong with him. They came and picked him up.

"I really care for him. I heard he had heart problems, so though it was a good idea to call the ambulance. That's what I learned at school - to call the ambulance when people need it. They told me to check if the colour of his skin had changed, if he was breathing and his medical history."

Jovi's mother, Chantel Beale, said she was impressed by how calm and quick thinking her son was.

"My daughter and I were at the gym for a couple of hours and I knew Jovi was fine to be home," she said.

"He said he had something exciting to tell me when I got home. I thought he had built something with his Lego then he told me about calling the ambulance for Rod across the road.

"I was dumbfounded. He was in his pajamas with bare feet and just took off across the road to see what was happening and then knew to get the home phone and call Triple-0."

Ms Beale said it was lucky Jovi looked out the window when he did.

"We have been neighbours (with Rod) for a long time. Jovi just saw him collapse (and) knew he had suffered a heart attack before, so he was aware that he wasn't well and thought to do something about it," she said.
