UPDATE: An Australian science paper I located from 1990 says that century scale sea level trends are 1-1.1 mm per year, and Sydney was 0.54 mm/ year. See below.

UPDATE2: a graph of the current SLR for Sydney is now available. See below.

From the Australian Telegraph:

SENIOR bureaucrats in the state government’s environment department have routinely stopped publishing scientific papers which challenge the federal government’s claims of sea level rises threatening Australia’s coastline, a former senior public servant said yesterday.

Doug Lord helped prepare six scientific papers which examined 120 years of tidal data from a gauge at Fort Denison in Sydney Harbour.

The tide data revealed sea levels were rising at a rate of about 1mm a year or less – and the rise was not accelerating but was constant.

“The tidal data we found would mean sea levels would rise by about 100mm by the end of the century,” Mr Lord said yesterday.

“However the (federal) government benchmark which drives their climate change policy is that sea levels are expected to rise by 900mm by the end of the century and the rate of rise is accelerating.”

Mr Lord, who has 35 years experience in coastal engineering, said senior bureaucrats within the then Department of Environment Climate Change and Water had rejected or stopped publication of five papers between late 2009 and September this year.

=======================================================

This paper by E.A Bryant in 1990 at the University of New South Wales has some interesting things to say. http://ojs.library.unsw.edu.au/index.php/wetlands/article/viewFile/166/228

UPDATE2: David Archibald provides this graph of Sea Level Rise for Sydney, Ft. Dennison from the long term data. The .5 mm trend/year shown above in the 1990 Bryant paper still holds. There does not appear to be any evidence of acceleration.

The NSW Govt. has a page for Fort Denison but you have to contact a data manager for the data: http://canri.nsw.gov.au/nrdd/records/ANZNS0001005063.html#metainfo
