Wonderful news for baby Gammy.

Baby Gammy, who was at the centre of a surrogacy scandal in Thailand, has been granted Australian citizenship.

Born with Down syndrome via a surrogate mother in Thailand, Gammy was left behind while his healthy twin sister Pipah was taken home by their Australian parents, Wendy and David Farnell.

The surrogate mother of the twins, 21-year-old Thai woman Pattaramon Chanbua, said she applied for Australian citizenship for Gammy because she wanted to safeguard his future, not because she wanted to travel to Australia.

Now Gammy has been granted citizenship he is also eligible for an Australian passport, although that is a separate process that has not begun.

It is unclear whether he could also be eligible for Australian welfare benefits.

Gammy turned one on December 23 last year, and has been undergoing treatment for a hole in his heart.
