Voting Alignment – Senate

How often have two Senate members — including former senators, not just those currently sitting — voted the same way on the same piece of legislation? Based on the Australian Parliament's own division records (aph.gov.au) — see About for the method. Senate and the other chamber can't be compared to each other: they never vote on the same motion, so there's nothing to compare — compare Representatives on their own page.
