An independent review will be undertaken by Associate Professor Sonia Allen who worked on similar reforms in South Australia.
Professor Allen's work was successful in allowing same South Australian sex couples access to surrogacy from last year.

A number of ethical issues will be probed including the genetic testing of embryos and the use of eggs and sperm if couples split or one partner dies.
