Australian stars have rallied around a petition calling for some of Tasmania’s forests to retain their World Heritage listing.

Geoffrey Rush, Mia Wasikowska and Oscar-winning costume designer Catherine Martin are among the famous Australians to sign a petition to save Tasmanian forests from losing their World Heritage listing.

The federal government is currently considering delisting huge swathes of the Tasmanian Wilderness, which is protected by its World Heritage status.

The government says much of the land has already been logged and degraded and could be used to benefit Tasmania’s economy

Now some celebrities have backed The Bob Brown Foundation’s campaign for the site to keep its place on the list.

Television personality Rove McManus, actor David Wenham and musician John Butler have also signed the Global Voices for World Heritage petition.

“I don’t want to be part of the generation that let our World Heritage Forests get destroyed,” comic and supporter Hamish Blake said in a statement.

“Having said that, I don’t want any generation ever to be that generation.”

Harry Potter star Miriam Margolyes, who now lives in Australia, musician Pete Murray and actress Jessica Marais are a few more of the campaign’s high-profile supporters.

Speaking on behalf of the campaign, McManus explained, “Tasmania is such a spectacular and special part of the world, every effort should be made to preserve all of its magic.”
