To cross the floor and vote against the party is to risk expulsion. 296 individual parliamentarians crossed the floor between February 1950 and April 2019. The Coalition participated in 96.8% of floor crossings compared to Labor's 3.9%. </p><p style="margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font-style: normal; font-variant-caps: normal; font-stretch: normal; font-size: 13px; line-height: normal; font-family: "Helvetica Neue"; font-size-adjust: none; font-kerning: auto; font-variant-alternates: normal; font-variant-ligatures: normal; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-position: normal; font-variant-emoji: normal; font-feature-settings: normal; font-optical-sizing: auto; font-variation-settings: normal;"><br></p><p style="margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font-style: normal; font-variant-caps: normal; font-stretch: normal; font-size: 13px; line-height: normal; font-family: "Helvetica Neue"; font-size-adjust: none; font-kerning: auto; font-variant-alternates: normal; font-variant-ligatures: normal; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-position: normal; font-variant-emoji: normal; font-feature-settings: normal; font-optical-sizing: auto; font-variation-settings: normal;">Senator Wong did not cross the floor in 2008 on a Green's motion to legalise same-sex marriage in the spirit of caucus solidarity. Senator Payman was suspended in 2024 after crossing the floor to support a Green's motion recognising Palestine as a state; she was the first Labor parliamentarian to do so in either house since 2005. </p><p style="margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font-style: normal; font-variant-caps: normal; font-stretch: normal; font-size: 13px; line-height: normal; font-family: "Helvetica Neue"; font-size-adjust: none; font-kerning: auto; font-variant-alternates: normal; font-variant-ligatures: normal; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-position: normal; font-variant-emoji: normal; font-feature-settings: normal; font-optical-sizing: auto; font-variation-settings: normal;"><br></p></span><br class="Apple-interchange-newline" style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0);">
