How "We can't say anything concrete about how they voted on" is worked out
Bob Katter has only voted once on this policy and it wasn't on a "strong" vote. So it's not possible to draw a clear conclusion about their position.
This could be because there were simply not many relevant divisions (formal votes) during the time they've been in parliament (most votes happen on "the voices", so we simply have no decent record) or they were absent for votes that could have contributed to their voting record.
