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

The big stifling in Oz is that of free speech. Gillard’s new law makes it illegal to state the effects of her carbon tax on prices. Maximum fine: $1,100,000
@crosspatch
yes, that’s a fascinating article, I’d just linked it on WUWT’s “tips and notes” before I saw that you linked it here….. one correction, it’s not by Judith Curry but by Tony Brown, and she posts a standard disclaimer that says she does not necessarily endorse any particulars simply b/c she’s posted the article…. but in any case it does fill in some fascinating context and detail…..
re: Judith Curry’s posting of the Tony Brown article, for sake of accuracy:
“JC note: For the last several months, Tony has been sending me snippets from his research. I find the climate-history nexus to be fascinating. I offered to post this on Climate Etc. As with all guest posts, the views expressed here are those of Tony Brown, and my publishing this here does not imply any endorsement by myself.”
Which makes perfect sense since over the past 2000 years, while we have had some ups and downs, we are generally in a cooling trend.

“I notice the Australian government are proposing a 20% increase in salary. ”
Julia promised that the revenue from the Carbon Tax would be finding its ways to the population, she just didn’t say on exactly which way.
The altitude of Toronto Canada is increasing by 25 mm/year, still rebounding from loss of the ice sheet which melted 14,000 years ago. Compare that to the miniscule 3.2 mm/yr sea level rise which is not accelerating due to man (at least not accelerating over the last 30 years).
Here is a graph referenced in the paper published today on Dr. Curry’s blog that shows a temperature reconstruction of the Alps in Europe going back 7000 years. A cooling trend can be clearly seen in the past 2000 years:

If this isn’t just a local phenomenon, which I believe it not to be local because we see glacial variation in North America at about the same time as that of the Alps, then I would expect sea levels to generally reflect the advance and retreat of Holocene glaciers.
That sea levels in Australia would generally reflect the decline of temperatures over the past 2000 years (albeit with variability reflecting the variability of temperatures) would be no surprise to me.
This is the equivalent of lying to the public by suppressing the advancement of science and the truth to avoid the consequences of unpopular legislation promoting a political agenda. The suppression of reviewed scientific work for such a reason is a form of persecution.
Shades of the trial of Galileo Galilei in 1633 .

Burns, could you (or anyone else) provide any links or sources to back this statement up? I’m intrigued

Australian Climate Madness
Julia Gillard introduced the tax based on a scam with a big fat lie. “There will be no carbon tax under a government I lead”.
Australia are not in the top 5 at Durban, we are alone with the tax, bring on the election.
STATE government bureaucrats have stopped publishing scientific papers which challenge Journalism School graduates’ claims about pictures of darkening steam featured in CO2 articles.
Fixed, for the gullible readers of this Sydney newspaper.

It is so obvious that this is political suicide that the question should be, what is it we do not see. What is the real plan behind this act.Call it conspiracy thinking ,But what if I’m right !
Argo bouys is not often mentioned. Maybe because they show a very, very inconvenient truth;

Thank you everyone for the links 🙂 Obviously none of you are climate scientists, what with your willingness to share information with those that enquire 😉 Chortle chortle 🙂

I can assure you Ray, with the Labor party in Government and the Greens with the balance of power, my beautiful Lucky Country is sinking at a much much faster rate than that.
crosspatch says:
Dr Peter Flood has showed that sea levels in Oz have fallen over the past couple of thousand years…
+++++
And in another case of nominative determinism (which abound in Oz for some reason) Dr Flood says sea levels in Australia….
You think we didn’t notice?
🙂
It is in line with what is shown by envisat “the inconvenient satellite”. Steven has several posts on it:
http://www.real-science.com/hiding-inconvenient-satellite
If one posts only envisat and removes all adjustments it gives a sea level rise of 0,33 mm – 3,3 cm per century!
One can select time series, envisat, gia not applied, seasonal signals not removed, inverted barometer correction not applied:

Interesting.

This is a little off topic, maybe maybe not. As I check your site on a daily basis and other sites; be it on this side of the AGW debate or on the other side of the debate, I noticed there has been little activity at Realclimate and Tamino’s blog and for some reason I cannot access desmogblog, but there vitriol seems accessible under the monicker “Progressive Blogger”. Any thoughts on the silence or they busy at Durban?
