Two friends suffered horrific injuries in a motorcycle collision at Lake Conjola early on Wednesday.
The men were riding unregistered motorbikes in opposite directions along Lake Conjola Road about 5.15am when they collided and were thrown off their rides.
A 25-year-old man later underwent emergency surgery to have his leg amputated. Last night he was in a critical condition.
His 20-year-old friend, who was not wearing a helmet, sustained serious head injuries and remained is a serious condition.
Both men were airlifted to St George Hospital.
