Large rainforest tree to 40 m tall, tapering from a stout trunk. Bark flaking in plates to produce an attractive mottling. Leaves dark, glossy green above, paler below, 5-12 cm long, 2-5 cm wide, the margins thickened and recurved, tapering into a flattened stalk. Male cones about 8 cm long, axillary, cylindrical, borne in the higher branches. Female cones 10-13 cm long, 8-10 cm wide, roundish, maturing and splitting up Mar.-Apr. to release the hard, flat bracts and seeds c. 8 mm long with an irregular wing on one side.

Qld. This species grows naturally in four localised areas: New Guinea to the east of Port Moresby, central New Britain, rainforests of N Queensland, and in SE Queensland on Fraser Island and the adjacent mainland.

Agathis robusta subsp. nesophila Whitmore is restricted in natural distribution to Eastern New Guinea and is not cultivated.

The timber was once used for furniture but is now in short supply.
