The CFMMEU is blitzing "tens of thousands" of voters with a robocall campaign attacking the Andrews government over its decision to end native forest logging in Victoria.

The calls, which feature the voice of a woman set to lose her job as a result of the government’s decision, began targeting regional voters around the state early this week with metropolitan electorates targeted on Wednesday and Thursday.

Premier Daniel Andrews announced last month that the logging of native forest timber in Victoria would end completely by 2030, with an immediate ban on old-growth felling, infuriating the industry and the CFMMEU, the logging union.

CFMMEU national secretary Michael O’Connor said on Wednesday the robocall blitz was "just the start of things" and that timber workers were in a rage over the policy change.
