Yes, I think now all land borders are completely mapped. Nice piece of work.

Good question, I would probably start with the national border. These
maritime boundaries are rather messy, just have a look at the yellow line
and the brown area in  or read the description there.
For this I see two different methods:
(a) Do the pure-OSM approach by deriving everything from the coastline with
some guessing for the straight segments.
(b) Try to get permission to use the official data 
Here I would definetly favor (b) - simply because to me the only accurate
definition of the baseline is the official one. But of course I don't know
at all if there is a chance to get the permission to use the data in OSM.
If this doesn't work we would have to work on using the coastline, somehow
generate a baseline, and from there calculate the territorial waters. The
piece looking most diffcult to me would be to generate the baseline, given
the topography of Australia's coastline and/or looking at .
Any thoughts or suggestions are highly welcome!
