New maps indicating areas vulnerable to flooding will not have an immediate effect on property values, according to the REIV.

A number of Sydney suburbs will be inundated regularly because of climate change-driven sea-level rises, threatening homes and community infrastructure worth billion of dollars by the end of the century, new projections show.
In the first detailed attempt to study the impacts of sea-level rises on low-lying coastal areas and help local government planning, the government has released high-resolution maps that show the areas in Sydney and the central coast most under threat from sea-level rises.
Sydney suburbs facing significant danger of inundation, even with limited rises, include Caringbah, Kurnell, Cromer and Manly Vale. Significant parts of Newcastle and the central coast are also potentially in harm's way.
And the problems associated with rising sea levels are not limited to coastal areas. Flooding could occur along the Parramatta River, threatening homes and infrastructure around Homebush Bay, Newington and Silverwater.

Along the Cooks River, Arncliffe and Marrickville could suffer, with the threat of significant inundation at Sydney Airport, too.
The maps show projected inundation for sea-level rises of 0.5 metres, which is likely to be unavoidable, 0.8 metres and 1.1 metres by 2100.
The projections combine rising sea levels and king tidal events, which can occur many times a year. The maps do not factor in protective infrastructure such as sea walls or show local effects such as beach erosion.
Tim Flannery, who sits on the federal government's Coast and Climate Change Council, said he had been struck by the significant effects on inland suburbs from river flooding in all major Australian cities.
Professor Flannery said he hoped the maps would drive a national strategy to co-ordinate Australia's approach to sea-level rises, including universal planning laws.
Bruce Thom, the chairman of the Australian Coastal Society, said the next stage of projections would deal with localised studies, including the potential damage from flooding events on land and storm surges from the sea, which he said would show the real risks of rising sea levels.
The Climate Change Minister Greg Combet, who launched the maps in Newcastle yesterday, said in a statement the government recognised ''that coastal areas of Australia are a priority for adaptation action, with many communities vulnerable to impacts such as erosion and sea inundation''.
Last year the government released data revealing that an estimated 247,600 buildings valued at $63 billion could be damaged or lost due to sea-level rises.
In the same data, up to 62,400 homes in NSW - worth $18.7 billion - were estimated to be under threat from inundation, mainly in the local government areas of Lake Macquarie, Gosford Wyong, Wollongong, Shoalhaven and Rockdale.
The maps released yesterday also include projections for low-lying areas in other heavily populated centres, including Melbourne, Brisbane, the Gold Coast and Perth.
Areas expected to be affected by rising sea levels include: Caringbah, Kurnell, Cromer, Manly Vale, Homebush Bay, Newington, Silverwater, Cooks River, Arncliffe, Marrickville, Sydney Airport, and parts of Newcastle and the central coast.作者: westice 时间: 17-12-2010 13:20

local的做法是及时行乐，平均每7年换一套房子，谁在乎100年以后啊，大概只有中国人担心这些事情，不过你千算万算要留给子孙后代，等他们在澳洲长大以后，根本不会要的，这个事情在一些六四移民的身上已经发生了。筒子们还是打算好住个若干年卖掉周游时间去吧。作者: nicoleflopy 时间: 20-12-2010 18:06
额，国外不是孩子长大了都净身出户的么。
另外，被海水淹没了自家的土地的一部分的时候，可以在海边建一个码头呢，或许还有些私家沙滩，哈哈
