Bor Mabil, 19, was one of five people in a white Audi sedan which crashed into a fence at Andrews Farm in Adelaide's north at about 12:30am.

The incident happened just hours before her brother took to the field for the Socceroos in their quarter-finals defeat at the Asian Cup in the United Arab Emirates.

"Early Saturday, Football Federation Australia (FFA) learned of the tragic passing of Bor Mabil, sister of Socceroos forward Awer Mabil, following a car accident in South Australia," the FFA said in a statement.

"FFA extends its deepest sympathies to Awer, the Mabil family, and Bor's friends, at this difficult time.

"FFA is providing support to Awer, his teammates, and Socceroos staff in the United Arab Emirates."

Police said Ms Mabil died at the scene of the crash, which happened when the car she was in collided with a fence on Andrews Road near the intersection with Lillypilly Walk.

Family spokesperson Manyok Ajak Mabil made a short statement to the media expressing the family's sadness.

"We as family and friends of Bor Mabil grieve at this time," he said.

"Bor was a great daughter and young woman with a great life ahead of her."

The driver of the vehicle she was in, a 19-year-old man from nearby Davoren Park, and three other passengers received minor injuries and were taken to the Lyell McEwin Hospital.

The man has since been arrested and charged with causing death by dangerous driving and driving while disqualified.

The driver of a second car, a green Toyota, which "was travelling in company with the Audi when the car crashed" has now been charged, police said in a statement.

The 18-year-old woman from Gawler West has been charged with causing death by dangerous driving.

Both drivers are expected to appear in the Elizabeth Magistrates Court on Tuesday.

Family fled South Sudan



Ms Mabil's family fled South Sudan and arrived in Australia as refugees in 2006.

Awer Mabil, 23, grew up in the Kakuma Refugee Camp in Kenya but later moved with his family to Adelaide's northern suburbs.

He made his debut for Adelaide United in 2012 and the A-League club has also paid tribute to Ms Mabil, sending its "sincerest condolences" to her family.

Awer Mabil later signed with Danish club FC Midtjylland and, at the time of his Socceroos debut last year, Ms Mabil spoke to the ABC about her family's pride.

"When he got the chance to go on it made us really happy," Ms Mabil said.

"He scored his goal which made it even better.

"He would have so much joy knowing he had made his country proud … and his family and friends happy."

Man woken by car slamming into fence

Isaac Shearing was asleep at the time but was woken by a loud bang, and got up to see his fence had been hit.

"We saw all the damage and I was worried … I could have been killed, my wife could have been killed, it was so close to our bedroom," he said.

"The retaining wall's taken a big hit, the fence is completely mangled, the greenhouse is totalled, a few garden boxes wrecked."

Mr Shearing said he had previously complained to the council about hoon drivers who drag race in the area.

"People hooning every night without fail. Something needs to be done and needs to be done now," he said.

Social media users have expressed their grief about the incident on Facebook.

"Their lives will never be the same now and this affects so many more than those involved in the crash. May she rest in peace," one wrote.

Traffic diversions were in place to allow Major Crash investigators to examine the scene, but Andrews Road has since been reopened.

Ms Mabil's death takes the state's road toll to 10, compared to five at the same time last year.
