'It's a shock for everyone,' Mr Kok said, according to the Herald Sun. 'We spent all night at hospital until 3 in the morning.' It comes as the tight-knit Sudanese community and nearby residents started leaving floral tributes for the three children. 'As soon as I saw the community coming towards this scene where the incident's happened, it's making me feel like people care,' Mr Kok said.

'Hopefully this will lead to a greater understanding of what led to this incident. We appeal especially to the Sudanese community who might know what was happening in this family's life, what their movements were before this tragedy.' A witness Michelle relived the tragic moment the car ploughed into the lake on Thursday morning. 'It is still in my mind now, every time you close your eyes you just see someone so little,' she told Nine News in tears. 'My heart goes out to the family and to everybody who witnessed it. 'Those rescuers, those workers, when it was winding down it was just devastating seeing them sitting in the gutter.' Michelle told 3AW late on Wednesday that her friend Travis rescued one of the young boys from the vehicle. 'Travis jumped into the water and smashed the back windscreen and got one little boy out.
