GROWING ANYWHERE from 3 metres to more than 8 metres long, the Australian scrub python, also known as the amethystine python is Australia’s longest python. And measured either by length or weight, it’s one of the six largest snakes in the world.

The Australian scrub python (Simalia kinghorni) is a species of snake in the family Pythonidae. The species is indigenous to forests of northern Australia. It is one of the world's longest and largest snakes, and is the longest and largest in Australia. Recently, it has been reclassified to the genus Simalia alongside a few other former Morelia species, but there is still a bit of scientific debate over this.

Scrub pythons have been known to attain a total length (including tail) up to approximately 7 meters (about 24 feet), with some field measurements claiming to be even longer, making this snake one of Australia's largest and longest snakes, if not, the largest and longest of Australia. This snake is commonly considered arboreal or treedwelling, making it one of the world's largest and longest arboreal species of snakes. This snake has an ornate back pattern consisting of browns and tans, with many different natural variations. Its belly is usually white, sometimes with some yellows.
