According to https://hotcopper.com.au/threads/ann-entitlement-offer-presentation.4651715/ "Record Date for the Entitlement Offer (7.00pm Sydney, Australia time) Thursday, 28 February 2019"; trades tomorrow won't settle before then so what you currently hold is eligible for the entitlement regardless of whether you sell it tomorrow or not. For the same reason anything you buy tomorrow won't be entitled.
