There is actually only one species of Dendrelaphis punctulata or the green tree snake that is native to Australia. There are many similar snakes, but only one actual green tree snake.
They're from very different groups, with many anatomical differences, most of which are very technical. Generally, boas and pythons are a group of 'primitive' snakes which retain vestiges of their hind limbs and have the ability to sense heat via lip pits, while green tree snakes lack hind limb vestiges and cannot sense heat. Pythons and boas are usually stockier and slower, but much stronger.
