The “collapse” of the government in a parliamentary system means the government no longer commands the confidence of a majority of the (typically) lower house, in this case the House of Representatives. Nothing immediate happens, although the prime minister may (or may not) resign, a “caretaker” government takes over until a new elections are held.

Here, it sounds like one of the four coalition parties has pulled out due to disagreeemnt over immigration, which the coalition parties had never agreed on.
