The interactive map of the Cooloola Coast shows the location of all the derelict vessels in the region. Another four derelicts vessels in the inlet have yet to be removed, and six more have been identifed as possible risks. Boaties are glad to see the back of them, but it comes at a cost. Noosa Commercial Boatman's Association spokesman Craig McGovern welcomed Maritime Safety Queensland's four-year, $20 million War on Wrecks program. He told News Corp, "abandoned, unsightly and unsafe houseboats have been a bone of contention... for decades". "They're a danger and they're polluting the river and they end up getting vandalised and the tinny rats get on them and make it worse," Mr McGovern said.
