My collapse hazard scenario for the WAIS is based on the assumption that we remain close to the Recommended Concentration Pathway, RCP 8.5 50% Confidence Level (CL) radiative forcing scenario developed by the IPCC at least until approximately 2045 (as the thermal inertia of the ocean will continue delivering heat to the Antarctic long after anthropogenic radiative forcing [eg: greenhouse gas emissions] are brought under control. Therefore, some people will say that following RCP 8.5 50% CL until 2045 is not likely and that you have nothing to worry about, while others will say that if we follow RCP 8.5 50% CL until 2045 you will have more to worry about from extreme weather and global economic/military consequences, than from the risk of abrupt sea level rise, ASLR, in your lifetime; however, I believe that ASLR will compound these other problems and will definitely have large negative affects on the next generation. Nevertheless, to give a more straight forward response to your question, the accompanying "Finger Print" map of the Greenland Ice Sheet, GIS, and the West Antarctic Ice Sheet, WAIS, ice mass loss contributions to regional SLR indicates that for Tasmania will not have any regional multiplier effect from the "Finger Print" effect for ice mass loss from WAIS, therefore, according to the graphs that I provide in the "philosophical" thread for the RCP 8.5 50% CL collapse scenario Tasmania may experience about a 0.5m SLR by the year 2060 and about a 3m SLR by 2100 (including all SLR contributions around the world not just from the WAIS). To get the final local effect on your risk of flood you would need to add on to of these values the short-term sea level factors such as tides, storm surge, storm tide, local land elevation changes, and regional variability in sea level (such as ENSO events or multi-decadal variations in sea level), as indicated in the second attached figure.
Good luck down under!
