I mean you shouldn’t let it exhaust because it makes your vote less powerful. Unless you genuinely think the Liberal party and Labor are exactly the same (which is insanity in my view). Also to be clear it’s still full preferential in the lower house. The upper house changed to require a certain minimum (I think it’s 6 off the top of my head) rather than the terrible party preference ATL. You can still do BTL if you can be bothered as well.
