In the wake of the anti-migration rallies over the weekend in this edition of The Conversation Hour we discuss the vital contribution migration makes to Australia, both economically and culturally, as well as debunk the argument that migration has caused the housing crisis.

Also in this edition, an inner-city bar has made light of choking in an advertisement, we discuss why it is problematic. Plus, with father's day just around the corner we discusses the important role of fatherhood.
