As we proceed through the last two sittings weeks before  June 30, those senators whose terms expire on that date are giving their valedictory speeches. Some, like Ron Boswell and Mark Bishop, who gave their speeches yesterday, are fixtures of the upper house and well known. Others have been on the red leather for a shorter period and their departure is unlikely to be as widely acknowledged.

In the case of Queensland LNP Senator Sue Boyce, who will deliver -- likely with her usual dry wit -- her valedictory this afternoon, that’s a shame. Indeed, it’s a shame she’s leaving the Senate, because Boyce, in her seven-year career in the Senate, has been an all too rare politician: thoughtful, brave, outspoken and prepared to stick to her principles.
