I agree. highway=motorway_junction is to mark where you exit the motorway.
An aside: Exits from the Hume Motorway/M5 have exit numbers now as you
approach Sydney.

In Sydney there are a few named interchanges which have a mix of tags
(highway=motorway_junction, tourism=attraction, place=locality), they
are all the same thing so I'd like to determine the best tags to use.

The wiki page for highway=motorway_junction
https://wiki.openstreetmap.org/wiki/Tag%3Ahighway%3Dmotorway_junction
is more about exit points along a motorway which may have a name or
number (ref), not so much for an interchange. So I don't think this is
the right tag to use. Plus JOSM warns it must be connected to the way,
which further confirms it's the wrong tag.
The proposed feature highway=junction
https://wiki.openstreetmap.org/wiki/Proposed_features/highway%3Djunction
looks like it's mapping out interchanges, so it seems like a better
tag, but it is less commonly used and still proposed. I'd prefer to
change them all to highway=junction, and better yet convert them to
areas.
I think it's fine to use tourism=attraction where it is such, like
Meccano Set, but it seems a bit of a stretch... Though this shouldn't
be the only tag.
What does everyone else think?
