Call of Cthulhu: Terror Australis – Rules of Play says:

This book contains two large scenarios and appendices:

• Long Way From Home: the investigators look into a series of odd and unexplained meteor showers and are drawn into a web of intrigue involving some ancient foes. Presented as a sandbox with multiple entry points, the scenario features a range of plots and encounters set in the remote region of Paralana.
• Black Water, White Death: sought-after papers concerning Australia’s convict history lead the investigators to Tasmania and to a dark mystery to terrify the dreams of all concerned. What begins as a simple matter of attending an auction ends with terror and a cosmic threat.
