Australis was a failed experiment from an attempt to create a creature capable of surviving in the vacuum of space. Failure to develop a suitable skin resulted in its exposed musculature. However, its self-healing properties and ferocious disposition make it a formidable foe to any that cross its path.
At twenty two meters long and seven meters tall, it is a formidable creature. The Australis are made from the DNA of a Tyrannosaurus. This one of the largest and most dangerous dinosaurs in the series, with its main comparisons being only the Cebalrai and Miaplacidus. Equipped with an electricity-generating organ, the creature releases shock blasts. Unlike T-Rex, however, it had two rows of teeth, sharing a trait with sharks.
The first Australis seen is also the 1st dinosaur seen. It ambushes the group when they enter the ship, but it's attention is then diverted when it hears something, that turns out vast quantity of hungry Rigels, which in an agonizing death eat the Australis alive from the inside out. A second was encountered by Patrick Tyler as he activated the Power Station.
The fourth Australis encountered was defeated in the Engines Sector thanks to the cooperation of Patrick and Sonya.
- It's roar was actually Jurassic Park's T-Rex sound effect, instead of the original roar used in Dino Crisis and Dino Crisis 2.
