[21] C. cunninghamiana, C. glauca and C. equisetifolia have become naturalized in many countries, including Argentina, Bermuda, Cayman Islands, Cuba, China, Egypt, Israel, Iraq, Mauritius, Kenya, Mexico, Brazil, South Africa, the Bahamas,[22] and Uruguay.

They are considered an invasive species[23][24] in the United States, especially in southern Florida[25] where they have nearly quadrupled in number between 1993 and 2005 and are called the Australian pine.

[citation needed] It is also an invasive plant in Bermuda, where it was introduced to replace the Juniperus bermudiana windbreaks killed by a scale insect in the 1940s.
