Back to your BOM data Hanrahan. If you read this document...
http://www.bom.gov.au/ntc/IDO60202/IDO60202.2009.pdf
...it clearly states that the following sea level anomalies, all postive, which means in ALL cases the sea level has risen since the measuring station was installed. I have extracted a few here from their Table 2:
"Location.........Installation Date....Sea Level Trend (mm/yr)
Cocos Islands..Sep 1992.............8.4
Groote Eylandt.Sep 1993.............7.5
Darwin..............May 1990.............7.7
Broome............Nov 1991.............8.9
Hillarys.............Nov 1991.............8.8
Esperance.........Mar 1992.............6.1
Thevenard..........Mar 1992.............4.5
...
Rosslyn Bay.......Jun 1992.............1.9
Cape Ferguson..Sep 1991.............3.0"
Point to take away - they are ALL ABOVE ZERO, even those I have omitted (for no reason except it is laborious to tranpose them manually). This means there has been a general sea level rise at ALL BOM measuring stations since they were installed.
Caveat as per the BOM: "Caution must be exercised in interpreting the 'short-term' relative sea level trends (Table 2) as they are based on short records in climate terms and are still undergoing large year-to-year changes."
This data from the BOM, all data points taken from "a state of the art sea-level measuring station" (your words Hanrahan), does not support your implicit assertion that there is no sea level rise.
