1 : After you sign up, you may have to wait for a day to get your account approved. If so then check back later. The following is after you can do something.

Look for a a driver with decent concentration (registering for the AussieWide section of the forum will give more accurate info). If there's multiple offers then you'll need to increase your bid a touch. No more than $2 million per race though.
If you're without a driver & are not sure if your bid will be successful, then log on Monday/Thursday night (Aust time) and make a 3 race bid on a cheap driver with no other bids against him.
3 : Sponsors You'll want to try to find yourself another sponsor.
