Yes wear a business suit with a jacket, for guys pants, tie, long sleeved shirt and jacket, shoes polished and no earings etc. Girls, matching suit with pants, skirt or dress, closed in shoes, matching bag and hair neatly done, with makeup and stud earings, only one or two rings on your hands, no necklaces or bangles etc and if you wear a watch make sure it's not a sports watch or anything with too much bling. Just remember you can never over dress for an interview! Good luck to everyone in Melbourne
