Non-government members, including crossbenchers, account for 92.8 per cent of all instances of disciplinary actions from 1901 to the end of the 44th Parliament in 2016—irrespective of whether Labor or the Coalition has been in Opposition (see Table 11).
Not that I’m inclined to defend the Coalition, but I suspected that the ratio was due to them being in opposition, and the historical record would seem to indicate that’s a large factor: https://www.aph.gov.au/About_Parliament/Parliamentary_Departments/Parliamentary_Library/pubs/rp/rp1617/DisorderlyConduct#_Toc468869261
Fair call. Both major parties need to lift their game!
