Malaysian-born woman Shaliza Zain Dewa, 45, and her Dutch-born husband Johannes van den Hende had been on holiday in Amsterdam with their children Piers, Marnix and Margaux, aged 15, 12 and 8. The family lived in Eynesbury, about 34 kilometres west of Hoppers Crossing.

While the official number of Victorians killed in the crash is 10, as many as 15 non-citizen Victorian residents are now believed to have died.

Piers, the eldest child, played soccer with Melton Phoenix Football Club's under-15 team.

Club president, Steve Williamson, said the club community was devastated by the loss.

''They were great people, really nice people, a nice family and down to earth,'' he said.

''It's unbelievable … the mood (at the club) is very solemn.''

Mr Williamson said the club had canceled an under-15s game scheduled for Sunday out of respect for the family.

Ms Dewa's mother Datin Siti Dina was at Kula Lumpur airport, where the family were supposed to change planes for the final leg of their journey, and told local newspaper The Star she had contacted Mr Van Den Hende's family.

''My friend and I watched the news on CNN as soon as I received the call,'' she said. ''I called up my son-in-law's family immediately.''

Marnix, 12, was a swimmer with the Melton Swimming Club, and had broken his personal best record for the 50 metres butterfly as recently as March 29, according to the club's website.

The children are believed to have attended Bacchus Marsh Grammar.
