A mid-air collision between two helicopters in Australia could have seen many more deaths.

A British couple and two Australians died in the crash today near Sea World on Queensland’s Gold Coast.

Three others – including two children – were seriously injured.

The cause of the crash is not yet known.

Officials say it happened less than 20 seconds after one helicopter took off from a sandbar and collided with another aircraft that was landing.

Australian Prime Minister Anthony Albanese said the country had been left shocked by the “terrible and tragic incident”.
