First revealed by the story depicted within the Team Fortress 2 comic Loose Canon, Australium is a metal element which can adapt and transform itself into different states and forms, therefore making it extremely valuable and sought-after.
Australium was discovered by the country of Australia, explaining the element's self referential name to the country.
The discovery of Australium has most likely been the cause behind Australia's rapid technological advancement. Said advances in technology include cloaking devices, teleportation devices, and the "entire spectrum of moustache sciences".
Australium is believed to be sold and exchanged within the form of solid bars, similar to the way gold is often reserved and stored. Despite sharing similar appearance properties to gold, such as a similar color and the level of reflectivity, bars of Australium can be identified by the unique logo of a lone figure boxing a kangaroo, one of Australia's most iconic animals. This act of boxing between the kangaroo and the figure is supposedly how Australia chooses their next rightful king.
Australians are known to be very secretive about Australium, most likely in order to keep the element in high value and demand, therefore allowing them to continue to outpace the rest of the world in the technological race.
Australium was also used in terms of payment to Dell Conagher's grandfather Radigan, in exchange for him building Blutarch Mann and Redmond Mann "Life Extender Machines" to further their own attempts to try and outlive each other to inherit all of the land given to them by their father. Radigan Conagher is believed to have found many more caches of Australium, and Dell later discovers hidden files detailing these caches amongst the blueprints Blutarch has lent to him to repair his own "Life Extender Machine".
It has been revealed that the United States once had a supply of Australium. It was all invested in the attempt to launch monkeynaut Poopy Joe into space. Following the tragic failure of this attempt, all the Australium went missing. As a result of the incident, Saxton Hale, whose facilities were used for the launch attempt, was brought before a U.S. Senate hearing investigating the disaster. As far as is known, the United States Australium supply remains missing.
Australium features in the game mode Special Delivery, as an Australium Briefcase.
It is neutral colored briefcase, that turns team-colored once picked up. It appears to be overflowing with items of clothing, has a radio transmitter attached to it, and has a transparent vessel attached to the side, containing a shining bar of Australium. When moving with the briefcase, a particle effect is emitted that shows several pieces of random clothing trailing behind the player, along with a golden sparkling effect.
Australium has been used in the creation of two rare weapons. When a player is killed by one of these weapons their body model turns into a golden statue that is left lying there for others to see.
