NSW Police have warned scammers are trying to cash in on the deaths of four young children, who were hit by an alleged drunk driver in Sydney at the weekend.

A spokesperson confirmed police had received numerous reports of online fundraisers soliciting donations for the children's funerals.

Antony, Angelina and Sienna Abdallah, and their second cousin Veronique Sakr, were killed when they were hit by a 4WD while they walked to get ice cream in Oatlands on Saturday night.

One fundraising page, hosted by GoGetFunding, is set up under the name of the children's mother, Leila Abdallah, but spells her son's name incorrectly.

So far, about $1,800 has been donated.

NSW Police urged the public to be vigilant when donating online.

"Do not donate via fundraising pages on platforms that do not verify the legitimacy of the fundraiser or that do not guarantee your money will be returned if the page is determined to be fraudulent," a police spokesperson said.

Those who have paid money to a scammer should contact their bank and police immediately.

Daniel Abdallah, the father of three of the four children who died, this morning returned to the crash site on Bettington Road to read tributes left by people.

People have left hundreds of bunches of flowers, as well as candles and balloons.

The children were all aged between nine and 13, and three of their relatives were also injured in the incident.

Among the teddy bears and other toys left for the victims were basketballs with prayers and messages of love for Antony.

In a statement, the college principal of Santa Sabina College in Strathfield described Veronique as "excited and full of anticipation" to start her new year at the school.

"Veronique had a smile for everyone and loved chatting and laughing with her friends," Principal Paulina Skerman said.

"She was involved in the social justice leadership team last year and showed genuine concern for others and was always willing to lend a helping hand."

A memorial service will be held at the school in the coming days.

Police allege Samuel Davidson ran a red light, mounted the kerb and hit the children.

The 29-year-old was charged with several counts of manslaughter, dangerous driving and high-range drunk driving.

Davidson is being held in a Western Sydney processing facility, and is isolated from other prisoners for his own protection.

Police claim Mr Davidson was three times over the legal blood alcohol limit.

The crash has prompted calls from medical experts to reduce the blood alcohol limit for drivers to zero.

John Crozier from the Royal Australasian College of Surgeons said stricter laws could help prevent more deaths.

However, NSW Police Minister David Elliott said it was unlikely drivers who broke current laws would comply with even stricter ones.

"A reaction like that based on Saturday night's tragedy is not correct because Saturday night's tragedy would not have made any difference if the driver had those laws to comply with," Mr Elliott said.

Mr Davidson's case was heard in court yesterday and was adjourned until April.
