It will save you time and reduce your chances of rejection if you research an agent’s submission style and business practices before approaching them.
When contacting agents, remember the basics: be polite, follow any submission guidelines and keep your communication clear and concise.
Before an agent agrees to represent a writer they will want to read the writer’s manuscript, so be sure to make contact only when you have something concrete to offer.
We also recommend that Australian authors approach Australian agents in the first instance. An overseas agent may wonder why you haven't got local representation.
