Agathis robusta, the Queensland Kauri or Smooth-barked Kauri, is a coniferous tree native to eastern Queensland, Australia, occurring in two localities, a southern population on Fraser Island and around Maryborough, and a northern population on the Atherton Tableland west of Cairns.

It grows straight and tall to 30-43 m tall, with smooth 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 species was heavily logged in the past, and spectacular large trees are now much less common than in pre-European times; despite this, the species as a whole is not endangered.

(Norwich BioScience Institutes) Scientists from the UK's Institute of Food Research have found a new possible explanation for why people who eat more fruit and vegetables may gain protection against the spread of cancers.They have shown that a fragment released from pectin, found in all fruits and vegetables, binds to and is believed to inhibit galectin 3, a protein that plays a role in all stages of cancer progression.
