Ornithorhynchus anatinus population genetics statistics for individuals sampled from the upper Yarra Victoria, northwestern Tasmania, King Island Tasmania, and South Australia. Samples from South Australia have been divided into categories to calculate genetic diversity in each of two groups: the most recent Kangaroo Island population (sampled from 2008 to 2009) and all Kangaroo Island and Warrawong Sanctuary individuals (sampled from 1991 to 2009). All individuals were genotyped at 13 microsatellite loci.

| Upper Yarra, Victoria | 60 | 9.00 | 5.76 | 0.549 | 0.597 | 0.08 | 0.646 | 5.077 (±3.499) |
| Northwestern Tasmania | 19 | 4.85 | 4.34 | 0.550 | 0.606 | 0.095 | 0.606 | 1.154 (±1.463) |
| King Island, Tasmania | 21 | 1.46 | 1.32 | 0.026 | 0.032 | 0.205 | 0.083 | 0.462 (±0.660) |
| Kangaroo Island, South Australia, 2008–2009 | 12 | 2.85 | 2.85 | 0.423 | 0.419 | −0.01 | 0.495 | 0.692 (±0.947) |
| Kangaroo Island/Warrawong Sanctuary, South Australia | 25 | 3.54 | 3.02 | 0.395 | 0.431 | 0.086 | 0.467 | 1.077 (±1.256) |
n, the number of individuals genotyped for each population; a, mean number of alleles; r, allelic richness; HO, observed heterozygosity; HE, expected heterozygosity; FIS, multilocus estimates; HWE, Hardy–Weinberg equilibrium P-values.
Significance after corrections for multiple comparisons. Locus; rA, mean number of rare alleles (frequency ≤ 0.05) per locus.
