Analysis of information sources in references of the Wikipedia article "Countback" in English language version.
Only unsuccessful candidates who contested the original election and who choose to contest the casual vacancy can be elected in a 'casual vacancy countback'.
On the other side of the aisle, Labor is negotiating a less consequential but electorally noteworthy difficulty arising from the retirement of high-profile former minister Alannah MacTiernan and the resulting vacancy for her South West region upper house seat. Such vacancies are filled through a countback of ballot papers from the previous election and not with the favoured nominee of the party, as in the Senate. The top three of Labor's six candidates on the South West ticket were elected in 2021, and in the normal course of events the countback would elect the next candidate along. However, The West Australian reports the candidate in question, John Mondy, is 'understood to be reluctant' to tear himself away from a successful Bunbury signwriting business to spend two years as a parliamentarian.
