In parliamentary systems, politicians are said to cross the floor if they formally change their political affiliation to a different political party than which they were initially elected under (as is the case in Canada and the United Kingdom). In Australia though, this term simply refers to Members of Parliament (MPs) who dissent from the party line and vote against the express instructions of the party whip while retaining membership in their political party (at least for the time being).
