Germany is one of the three competitors.
Large German company ThyssenKrupp Marine Systems (TKMS) is offering the Type 216 submarine to Australia. "ThyssenKrupp Marine Systems Australia Pty Ltd" is listed as a Member of the German-Australian Chamber of Industry and Commerce in its "Member Directory" (see under "T" or "Thyssen" http://australien.ahk.de/en/members/member-directory/?no_cache=1 ).
