Adult Uluru skinks pair for consecutive years and may raise several generations in a single burrow constructed by the parents. Not unlike humans, multiple generations of skinks live in the shared home, with parents and children contributing to the maintenance and expansion of their home. The burrows are up to thirteen meters in length, have twenty entrances, and contain designated latrines. Researcher found that skink families inhabited them for up to 7 years straight.

DNA testing of Uluru skinks reveals that young lizards sharing the same burrow are nearly all full siblings, who delay leaving the burrow to care for the family home. According to Macquarie University researcher Dr. Adam Stow this cooperative living arrangement is remarkable for lizards: "It’s an unusual case of parental care and also having the siblings cooperate [that] make[s] them possibly the word’s most social lizard."
