What happens if a MP leaves parliament? Do they get replaced?

Yes, you’re right! If a member of the House of Representatives resigns or dies between federal elections, they will be replaced in a by-election. A by-election is a an election held to fill a single vacancy in the House of Representatives outside of the regular 3-year election cycle.
