In NSW the anti-vaxxers remain nowhere politically.
I read today that the Riverina has passed the 97% first jab threshold. This has occurred in a Nationals / Fishers & Shooters heartland that also delivers some support to ONP candidates.
Once jabbed, conservative voters (like everyone else) move on from the issue. I doubt that anti-vax radicals will get any measurable support in the upcoming LGA elections.
