IMVHO trading halts are designed for this purpose.
If they have something to announce (and we know what that might be) they go into a 48hr halt that can then be extended semi indefinitely.
Gives them time to make the lodgement properly even if it takes to say to the end of next week. However, given the impending W/E, they will probably make the Tue start.
