In southern Australia, breeding usually happens from late winter to early summer (August to January). In other places in Australia, breeding has been recorded in every month except March. It depends on changes in food availability and climate. Nesting sites can include hollows of tall trees such as eucalyptus, palm trunks, or overhanging rock. One lorikeet population in the Admiralty Islands nests in holes in the ground on predator-free islets. Pairs sometimes nest in the same tree with other rainbow lorikeet pairs, or other types of bird. Rainbow lorikeets lay between one and three eggs, which are incubated for around 25 days. Incubation is carried out by the female alone.
