Today's SMH has some more info on why the ocean being searched is pretty much free of debris as was being discussed earlier:

University of Western Sydney oceanographer Charitha Pattiaratchi said the area where the images were captured and where wooden pallets and straps were seen was outside normal shipping lanes and distant from circular currents in which waste often accumulated.
''Usually things that have been in the ocean for a long time are either under the surface or sink or break down into much smaller pieces,'' Professor Pattiaratchi said.
''To see a large object like that, then certainly it is credible [it is wreckage]. It is extremely unusual.
''Each of the oceans has what's called a big gyre [circular current] and usually any debris goes around this gyre and sometimes they accumulate in the centre, but the search area is thousands of kilometres from the region and we are in a different system.
''The southern Indian ocean is an area which is relatively free of debris.''
Finding the objects should be a priority as technology could then be used to determine how currents had moved the objects during the past two weeks, Dr Beaman said.
