In Papua New Guinea the typical subspecies has been recorded from a small area near Port Moresby. The second subspecies (A. robusta ssp. nesophila Whitmore) occurs in various localities in the Owen Stanley Range as well as in New Britain. These subpopulations are sometimes referred to as Agathis spathulata de Laub.
The overall extent of occurrence for A. robusta exceeds 20,000 km2. The total area of occupancy is estimated to be less than 500 km2. There are 8-10 locations.

Habitat and Distribution
It occurs in two localities, a southern population on Fraser Island and around Maryborough, and a northern population on the Atherton Tableland west of Cairns; the northern population was formerly distinguished as Agathis palmerstonii, but does not differ from the southern population and is no longer considered distinct (Whitmore 1980). Trees in Papua New Guinea previously referred to Agathis robusta are now treated as a distinct species Agathis spathulata (de Laubenfels 1988).
It is a large evergreen tree growing straight and tall to a height of 30–50 m, with smooth, scaly bark. The leaves are 5–12 cm long and 2–5 cm broad, tough and leathery in texture, with no midrib; they are arranged in opposite pairs (rarely whorls of three) on the stem. The seed cones are globose, 8–13 cm diameter, and mature in 18–20 months after pollination; they disintegrate at maturity to release the seeds. The male (pollen) cones are cylindrical, 5–10 cm long and 1-1.5 cm thick.
The Queensland Kauri was heavily logged in the past, and spectacular trees of prodigious size are much rarer than in pre-European times; despite this, the species as a whole is not endangered.
