A 28-year-old Buddina man has died at Mountain Creek after the motorcycle he was riding crashed into a tree.
Just after 7.30, the black Suzuki motorcycle was travelling along Karawatha Drive when it attempted to merge with traffic, lost control and hit a tree, west of the intersection with Lady Musgrave Drive.
Witnesses stopped and rendered first aid and conducted CPR on the man before emergency services arrived.
He died a short time later.
Officers from the Forensic Crash Unit are continuing investigations.
