In fact, I almost expected an import to attempt to create the
tablespaces and users from an export file as required?

The import will create users but will not create the Tablespaces.

To see exactly what the import will do, execute the following statement, it
will not import the file, but will show you what would happen if you did:

imp user/password@TNSName myfile.dat show=Y log=mylogfile.txt

This will output mylogfile.txt with all the create commands and sizing
information for each of the segments to be created.
