This doesn't happen and has never been documented. There is no evidence of
this event as an Arunta (or any other aboriginal group) "social strategy."
However, what evidence there is of Arunta social strategy proscribes against
"widespread sexual activity," which directly contradicts your claim.

Service provides for no such "walkabout" class, act, or custom, and
therefore it is not evidence of any Arunta "social strategy." Thus your
prediction based on this imaginary process is simply groundless and
contradicted by documented aboriginal social strategies of exogamous local
kin groups with cross-cousin marriage and particular lineal residence
Therefore, low population doesn't correspond with social strategies to
increase gene flow in the Arunta case. Your hypothesis lacks any supporting
evidence and is falsified by known social characteristics of the central
