Ten injured in three-car Brisbane crash

Ten people, including four children, have been involved in a multi-vehicle crash in Brisbane's west.

Three vehicles collided on the Brisbane Valley Highway, near Fernvale, on Wednesday afternoon.

A 40-year-old man with chest and shoulder injuries and a five-year-old boy with chest pain were the first patients flown out by rescue helicopter.

They've been taken to the Princess Alexandra Hospital in Brisbane.

Shortly after, a 27-year-old woman with arm injuries and a six-year-old girl suffering from abdominal pain were also being flown out.

Six others - including an infant and two young girls - have been taken to Ipswich Hospital with minor injuries or for further assessment.

The affected stretch of the highway has been closed off, with diversions in place south of Fernvale.
