Ann: Share Purchase Plan, page-54

I have a question and its probably a simple one so sorry for being annoying. This is the first time I think ill try go for a full allocation. Obviously like everyone thinks its probably going to be scaled back.
q1. No matter how much i put in will it get reduced? Ie if i go 2k then thatll be reduced so i should always go 30k and try get as much as possible?
q2. If i go 30k and its reduced say to 10k they send a physical cheque for the 20k or is it electronic? Id be a bit nervous having 20k in a physical cheque just going through the australia post

thanks all
