Mothers with newborn calves often shelter in the calm waters immediately outside Swallows Cave between July and October. Boat operators hold outside the 100-metre exclusion zone, but encounters near the entrance are not uncommon during the breeding season.

How is this calculated?

Sighting evidence is compiled from iNaturalist observation records within a set proximity radius, filtered for quality-grade observations. “Last confirmed” is the date of the most recent research-grade record. Record count covers a rolling 24-month window. Confidence reflects record count, recency, and consistency of seasonal signal.
