Sportsbet.com.au provide a list of runners for the next few days. They also provide a list of horses that are, or might be, nominated for some of the feature races to be run over the spring.

I have a spreadsheet that I've formulated to identify the nominees that are running each day. The list is usually a lot smaller during week days rather than weekends.

(plus I got a bit impatient to wait for Racenet to identify them for me).
