Seven people have been injured aboard an international Qantas flight to Sydney after the aircraft was hit by severe turbulence.

QF32 had departed London on Friday night and was three hours out of Singapore on Saturday morning when it was hit by turbulence caused by bad storms in the Indian airspace, a Qantas spokeswoman said.

"(The aircraft) diverted around most of it but it was the initial part of the storm that had the impact," the spokeswoman said.

"The seat belt sign had come on but some passengers were still moving back to their seats."

Seven people suffered minor cuts and bruises during the incident.

Four were treated in hospital while three were treated at a medical centre in Singapore but all have since been discharged.

The aircraft was cleared to fly after being assessed by engineers and has departed Singapore.

The flight is due to arrive in Sydney at 9pm on Sunday.
