No , Aus Post is not exempt . If the mail is not addressed to a persons at the address complete with their postal address then that is deemed to be junk mail under the act and should not be delivered . I have reported AusPost more than once to the DEHP for dropping large amounts of unaddressed junk mail into my no junk mail letterbox . <| sep |> I think it ' s reliable when stock is added , but it ' s still tricky . I went out to WM when this weird , conflicting information message was listed on the WM two miles from my house . If nothing was there , no problem . But it was there , and I got one . That said , it was still listed as conflicting info hours later . <| sep |> Pointless statistic as you don ' t need to complete act 4 due to no reward for doing soAlso , finishing act 4 is not a requirement for mapping .
