Both of my Garmins (GPSmap 76CSx and Nuvi 1350) have displayed this 
problem with the coastline and OSM maps for a while.  I first noticed it 
about 4-6 weeks ago, but it could have been there for much longer 
without my noticing.

I'll be downloading the Oceania file from 
http://download.geofabrik.de/osm/australia-oceania.osm.bz2 tomorrow 
morning and making a new Garmin map from it.  I'll report back on the 
status of the coastline anomaly.
