They may, given that it clearly states in the document checklist to not submit these documents with the application, that they will be requested later on. Keep in mind that the police check has an expiry date. They may return the application or request that you re-submit the schedule A and the police certificate, so might not be a bad idea to request it again.
Thanks heaps! My police cert will expire a year from now. Im just worried if giving them docs in advance will be a bad idea
