Queensland Coast — Pre‑European Peoples

The people represented by these three samples lived along the tropical coastlines and river systems of North Queensland during the final centuries before broad European disruption. Archaeological data indicate long-term human presence in the region, with continuity of coastal foraging, shellfish processing, and stone‑tool traditions that tie into much older Sahul occupations.

Sites tied to these samples — the Mulgrave District near Cairns and locations around Weipa on the Cape York margin — sit in landscapes rich in mangroves, estuaries, and reef-associated resources. Limited evidence suggests seasonal rounds that combined fishing, the gathering of shellfish and edible plants, and inland excursions for stone and plant resources. Radiocarbon-dated material associated with human deposits aligns with the 410–1788 CE span assigned to the genetic samples.

Because only three individuals were sequenced, these data provide a tentative glimpse rather than a definitive origin story. Archaeological continuity at named localities supports long-term residence, while the genetic signatures hint at maternal lineages that have deep roots in the Sahul population. Further integrated excavation and community-led sampling are essential to build a fuller picture.

Genetic data from three pre‑European individuals provide a narrow but informative window into maternal and paternal lineages in North Queensland. Two individuals carry mtDNA haplogroup P and one carries M. Haplogroup P is known from ancient and present-day Aboriginal Australian populations and is often interpreted as a deep Sahul maternal lineage. Haplogroup M likewise represents an ancient branch found across Australia and nearby regions.

The single male Y‑chromosome recovered belongs to haplogroup F. Because F is a broad, deep clade that branches into many downstream groups, a single F result cannot reliably characterize regional paternal diversity; many Aboriginal Australian Y lineages elsewhere belong to C, K, or S lineages, and the absence of those in this tiny sample may simply reflect chance.

Crucial caveats: with only three genomes, statistical power is extremely limited. Archaeogenetic insights are best treated as hypotheses that align with archaeological continuity rather than definitive demographic statements. Nonetheless, the maternal continuity suggested by two P lineages corroborates local persistence of deep Sahul ancestry in North Queensland. Future, ethically guided sampling with Indigenous partnership will be necessary to test population structure, sex-biased mobility, and connections to neighbouring Aboriginal North Queensland groups.
