That's fair, I was talking specifically about Melbourne. However, the redistribution doesn't account for the swing against Bandt. The ABC's analysis put his first preference vote nominally on ~45% after redistribution, but he only got 39.5% (and I believe their swing figures are adjusted for redistributions, which is why they show Bennelong as a Labor gain from the Liberals even though Labor previously held the seat).

You're completely right about Brisbane though (and the same thing nearly happened in Ryan). The swing against the Greens alone wouldn't have dropped them out of the 2CP, the massive surge for Labor at the expense of the LNP was what did it.
