For Victoria and New South Wales, if the registration number and year are stated in the citation, the record can instantly be looked up on the search page by entering the numbers in the appropriate fields. Contrary to what Aleš says, there is great value in giving a link to the search page: it allows the reader to check easily that the citation is correct. Of course, this only works if the link is valid, so running EditBot to update old versions of the links makes perfect sense.
