Eli five-year-old sister Nicola pinned under a wall for more than an hour after the tree fell on the living room . I was trying to get to him - that was my only concern, Mr Marnock told Daily Mail Australia. He had two storeys worth of debris and a tree on top of him. There was no hope, I just couldnt get to him. It was a complete feeling of absolutely helplessness. The extent of the damage meant Mr Marnock and rescue workers couldnt access Elis bedroom until after midnight. I stayed there until I got him out, he said. I had the firies fire service officers with me, we ended up going through the wall in our bedroom cupboard. And the tragedy could have been even worse. Mr Marnock said it was a nap in the car that saved the life of Elis five-year-old sister Nicola who wasnt tired and was on the couch watching TV instead of sleeping in the bedroom she shared with her little brother. The tree destroyed the home at The Patch, in the Dandenong Ranges east of Melbourne, just after 9pm . Mr Marnock said he was devastated by the loss of his cheeky little boy who was his little dude Earlier that day the family visited Mr Marnocks fathers grave as it was the fifth anniversary of his death. When the family was back at home that evening, Nicola was on the couch watching TV and Mr Marnock and Elis mother Suzie Surridge, 37, had walked to the front of the house to investigate the storm. We had actually stood up to go and look out the front door because we heard the gust of wind, Ms Surridge said. We opened the front door but had to close it immediately because of the wind. Nicola had stayed sitting in the armchair then all of a sudden the tree from above us just came down on top. Ms Surridge said she and Mr Marnock were in an archway which protected them from the debris, but Nicola was trapped under a collapsed wall.

Emergency Services Minister Jane Garrett said it was the councils responsibility to make sure trees located near houses were safe, amid reports neighbours had complained about the size of the tree . We were able to get across over the debris to where Nicola was pinned, fortunately the angle of how things had gone down it didnt crush her upper chest or head, she said. I was able to sit and speak with her and keep her talking the whole time. Mr Marnock said Nicola was a little trooper throughout the terrifying ordeal. She was just amazing, he said. She got stressed out at times and she was a little bit concerned as to where Eli was - she knew she couldnt see their bedroom door. It took an hour for rescue workers to free Nicola. She was taken to hospital where she was treated for injuries including bruising and a torn liver, but she did not suffer any broken bones or haemorrhaging. Mr Marnocks 13-year-old son Jesse, who was in a hallway when the tree came down and was not injured, ran up the street to get help from neighbours before the emergency services arrived. Ms Surridge said Elis death was going to hit his brothers and sisters hard, and she was struggling to come to terms with the tragedy . Ms Surridges parents John and Sue Surridge were at the rear of the property, where they lived in the back part of the dual dwelling. Mr Surridge was trapped in a room for two hours before rescue workers got him out . He was absolutely amazing - he was able to go up into the back section of house where Grandma Sue was and was able to vocally communicate with Grandad John because we had no visual, Mr Marnock said. He helped me so much, he was my legs. He was my star, he was just brilliant. For a 13-year-old kid to do that is just amazing.
