The Older Peron transgression was one of a series of gradually diminishing marine transgressions during the middle Holocene. It was followed by the Younger Peron, Abrolhos, and Rottnest transgressions. During the Younger Peron transgression (c. 4000–3400 BCE), sea level peaked at 3 meters above the twentieth-century level; during the Abrolhos (c. 2600–2100 BCE), 1.5 meters; and during the Rottnest (c. 1600–1000 BCE), 1 meter.
At least a few commentators — anthropologists, folklorists, and others — have linked era of the Older Peron transgression and the Neolithic Subpluvial with tales of a "time of plenty" (Golden Age; Garden of Eden) that occur in the legendary backgrounds of many cultures.
