This comment has no substance "The WA State Government has researched this issue thoroughly and the reccomendations to remove the shacks is a good one." Source of information?
The Government's interest in Wedge Island lies not with the environmental impact but rather with the potential financial loss. If Wedge Island is destroyed it will eventually be developed. Inflicting far greater environmental damage. In the official release by a WA Legislative council in "April 2011 found that coastal shacks should be removed to protect the environment from "unplanned growth".".
"Unplanned growth" being that which they do not benefit from. Furthermore there was a ban on expansion to shacks placed over 15 years ago. Since then no new shacks have been built therefore no threat of any future "unplanned growth".
This same government funds and allows the military facility just South of Wedge Island (same natural habitat) to bomb the land. I don't even need to get into the environmental impact of this.
