The crash happened on Christie St in St Marys about 3.20am on Friday.
Emergency crews worked to free the woman and her five-year-old son who were trapped inside their Hyundai Getz.

The boy was treated at the scene by paramedics before being taken to the Children’s Hospital at Westmead in a critical condition.
The 38-year-old woman was also treated at the scene and then taken to Westmead Hospital in a critical condition.
“Police have established a crime scene and are investigating the cause of the crash,” police said.
Local business owner Frank Jenneo said he always feared a major crash would happen if trucks weren’t banned from parking in the area overnight.
“Driving at night it’s not lit up, and if you don’t know the road, and you don’t know the trucks are there and something happens, and you lose a bit of concentration, you’re likely to hit one,” he told 7NEWS.
“It’s a death trap … this is an accident that’s been waiting to happen for a long, long time,” he said.
