Los Angeles: It appears the campaign to merge Australia and the US to form one nation called Ameristralia is as doomed as the Tasmanian tiger.

Despite an online push in both countries, a petition on the official White House website only generated six-and-a-half-thousand signatures.

The deadline to receive 100-thousand signatures expires on Friday.

The Ameristralia campaign was born on the social news and entertainment website Reddit, where supporters created a coat of arms featuring a bald eagle's body with a koala's head.
