The whole of the Australian coastline, in OSM XML, is roughly 110 MB.
JOSM can open this file in one go - I hesitate to say "with ease", that
would perhaps be too much on the marketing side ;) you will require a
fast machine with 2GB+ of RAM and/or some patience but if the problems
you see are of a kind that can be fixed by the Validator, then this
might be the way to go.
You could attempt to get a current version of the coastline data through
XAPI, or else grab a (very current) Aussie extract and run
osm-excerpt-tags on it to reduce it to coastline only. (Opening the
whole of Australia in JOSM would not work.)
Merkaartor is likely to be quicker with large files but I don't know if
it has an error detection/fixing facility like the Validator plugin for
