Labor has lodged a complaint with the Australian Electoral Commission over Liberal signage targeting Chinese voters that appears to imitate official AEC communications.

The signage appeared in the key marginal seat of Chisholm - previously held by Julia Banks - which has a high Chinese population.

The corflute uses the same purple colour scheme as official AEC banners and tells readers the "correct" way to vote is to put a "1" next to the Liberal box.

However, the Electoral Commission has dismissed concerns about the signage, saying it is allowable as long as it carries proper authorisation and is located in an appropriate spot.
