If you have to ask it may be too late
The National Health and Medical Research Council advises its research help desk, “is experiencing a significant number of inquiries close to the closing dates of grant applications.” Funny that.
The council suggests applicants talk to their research administration officer in the first instance about synergy grants but if they do ask the help desk to allow 72 hours for an answer. With a May 1 deadline and a weekend and ANZAC Day in the way new questions better not be grant-breakers.
