Legislation
Neither the surrogate mother nor the married couple are legally protected in any way. If the girl changes her mind about giving the newborn, the biological parents will be left with nothing.
There are no fertility treatment programs that guarantee a successful IVF outcome. It means that for each subsequent IVF atempt, the married couple will have to pay, as а result, a considerable amount accumulates, which is too much for many.
Australian doctors asked Australian government to legalize commercial format of surrogacy. Doctors reasoned their request as follows: conditions for carrying pregnancy and childbirth on the continent are many times better than in foreign countries, where Australians go to treat infertility.
Australian women are reluctant to become surrogate mothers, so infertile couples leave the continent for other countries where such technology is controlled by law.
Surrogacy on the continent is available to gay couples (except in Western Australia, where only heterosexual couples can use surrogacy services). In South and Western Australia, same-sex couples are allowed to adopt children.
