A couple of other things that those who do not use Austote at the moment should note:

They don't field all races --- none today as far as I can see.

They do indicate how much has been invested in the pool at any moment

The Virtual FormGuide shows Austote's pool and the pools for the three mainland totes together, and that service is free

Unfortunately they do not take place bets (again, in so far as I can see)
