This episode ended with a tribute to Tony Barry, who played Joseph in season one. Barry died after completion of filming and did not live to see the season's release.
In the post-credit scene, a character whose face is not seen (listed in the credits as "Russian Oligarch "), presumably Johann's crime boss, demands (in Russian) to know where Tasmania is, and checks its location on a globe. This could be a cliffhanger for the second season.
