Two children orphaned in a horrific crash involving their family's four-wheel-drive and a road train on Friday have received an overwhelming show of support from their tight-knit community.
Lara and Mark Dawson, from Tom Price, were killed when their 4WD collided with the road train around 3pm on Great Northern Highway in the Pilbara.

Their two children, Larissa and Jack, were seated in the back of the vehicle, with the family on their way to embark on a school holiday trip to Broome, caravan in tow.
The teenagers survived the crash, and were taken to hospital as a precaution.
A fundraising page set up to support the children has raised $35,000 in one day.
Narelle Johnson, who created the page, urged the community to "band together to help support the kids in this difficult time".
"Lara and Mark were both very active in our community and would have done anything to help anyone," she said.
It is understood the children are being cared for by extended family.

Major crash is investigating the deadly crash.
A police spokeswoman said the family were approaching a reduced speed roadworks zone when a cattle truck travelling behind them collided with their caravan, forcing the 4WD and caravan onto the wrong side of the road and into the path of an oncoming Toyota Prado.
The 4WD struck the Prado, detached from the caravan and rolled several times down an embankment.
The caravan carried on and struck an iron ore road train travelling in front of the family.
Around 120 cattle were killed as a result of the crash.
The iron ore road train driver and Prado driver received minor injuries while the cattle road train driver was uninjured.
