These bugs were photographed in my parents back garden on the island of Borneo, Indonesia. Any idea what they are?

Hi Victoria,
The magnificent beetle is one of the Hercules Beetles in the subfamily Dynastinae. They are also known as Rhinoceros Beetles. Eric Eaton just provided this correction: ” The Borneo “hercules beetle” is actually an “atlas beetle” in the genus Chalcosoma. The specimen is a male, and the genus is in the hercules subfamily Dynastinae.”
