Aventure en Australie, written by Tome and drawn by Janry, is the thirty-fourth album of the Spirou et Fantasio series, and the second of the authors.

In Adventure in Australia, the Count of Champignac, accompanied by a young professor, Walker Donahue, thinks he has made an extraordinary discovery in Australia, namely an immense indigenous monolith in the surroundings of a mining village.

Thanks to the aboriginals, of which they were allies, Spirou, Donahue and the Count put in rout Sam's men who are trying to eliminate Fantasio and Seccotine.

Finally, the monolith is discovered and the aboriginals make an agreement to share resources with the prospectors, who are grateful to them for getting rid of Sam.

Adventure in Australia was made into an episode of the animated Spirou et Fantasio TV series.
