An 18-year-old Singaporean student has died in a gyrocopter crash in Victorian bushland, according to Australian reports.

Mr Jordan Pang, who was a passenger, was killed on Saturday evening, along with the pilot Reg Thaggard, 51.

Their bodies were found in Kinglake National Park, 50 kilometres from Melbourne, early on Sunday morning.

Mr Pang was living in Melbourne and was reportedly due to return to Singapore at the end of the week. He had reportedly just finished high school and was taking photos of the picturesque bushland to show his family.

Kinglake National Park is a popular venue for gyrocopter flights.

Mr Thaggard was said to be a highly experienced pilot.

Authorities are still trying to uncover the cause of the crash.

There were two previous gyrocopter crashes this year, including one which hit a wallaby during takeoff.
