In Westminster parliamentary systems the opposition is the largest party or coalition that is not the governing majority party/coalition. There can be other parties or individual members in the parliament that are not part of the government or opposition, in Australia they are known collectively as the crossbench (referring to how they are seated on the benches between the government and opposition benches in the parliament chamber).

Fucking bullshit, but entirely unsurprising that a cop gets away with a slap on the wrist for something that would put anyone else away behind bars. NSW has never truly moved on from the Rum Corp
