Choose a seed mixture that has been made for the bird that you have purchased and make sure they always have a good supply, fresh water every day, also greens, fruit, shell grit and cuttlefish. If buying from the breeder always ask what foods they recommend for the bird you have just purchased. Lorikeets need special food so be sure to take some home with the bird. In Victoria there is now a minimum size for the cage to keep a pet bird in, possibly the other States will adopt similar regulations. If you are planning to purchase a new cage it would be wise to get one in the recommended size for your bird, or larger, no matter in which State of Australia you live.
Birds love to climb so it is better to have the bars on the sides running horizontal if possible.
It is best to have a wire floor with a tray under it. Two perches should be fitted, one each end, as thick as a broom handle, natural branches are best. If building your own cage at least one long side needs to be all wire.
