Sell your seaside Australian Property Now!

At Port Arthur, this published paper - below - estimates an ocean rise of 1mm per year.
Well, I'm not much with figures, but I think that means 100mm in a century.(4 inches)
At WA's Fremantle - 1.6mm pa or 160 mm in a century. (6 inches)
Fort Denison (Sydney Harbour) 1.2 mm per year or 120mm per century. (under 5 inches)

For Australians and other metric countrymen, who are not sure on the imperial measurements, 6 inches is half a foot. Al Gore’s movie ‘An Inconvenient Truth’ says sea levels could rise up to 20 feet. Is this true? Forty times greater than the above!

Myth Busted!

When combined
with the estimates of land uplift given above, this yields an estimate of average sea level rise at this location due to an increase in the volume of the oceans of 1.0 ± 0.3 mm/year. This is at the lower end of the range of global average sea level rise for the 20th century (1–2 mm/year) given by the Intergovernmental Panel on Climate Change [Church et al., 2001]. If it is assumed that most of this sea level rise occurred since about 1890 (the indication from long tidal records from elsewhere; Woodworth, 1999), then the corresponding estimates of rise (1890 to the present) relative to the land, and due to an increase in the volume of the oceans, become 1.2 ± 0.2 mm/year and 1.4 ± 0.3 mm/ year, respectively.
9. Discussion
[13] The above estimates of sea level rise due to an increase in the volume of the oceans may be compared with recent estimates for the two longest (continuous) Australian records. Fremantle (32 30 S, 115 440 E; 91 years to 1996) and Fort Denison (33 510 S, 151 140 E; 82 years to 1997) showed rates of rise of 1.6 and 1.2 mm/year, respectively, after adjustment for GIA [Lambeck, 2002].
