If your skink is properly taken care of, it should be able to breed at about 2 years of age. Before breeding you have to check and make sure their tail is large and has an excess store of fat inside. It is permittable to keep all of the females together, but only if one male is with them. The blue-tongue breeding season falls between January to early spring. To help induce the breeding the skinks should kept at a temperature of 13c to 18c for 2 months. If the male skink becomes violent during the breeding time, do not worry, this is common. Fights may break out and because of this it is advisable to keep the animals separated until breeding time.
