Selwood (7.50), Judd (3.75) and Barlow (181.00) are more than generous top 5 odds from Sportingbet.
It seems the maximum payout is 10000.00 as I could only get 55.00 on Barlow at the 181.00. I don't think he'll be top five, but if he polls as if recognised from round one, I have him on a maximum 21 votes. It's unlikely he'll poll 'well', but even the mid teens could see him at least tie for fifth.
Then put 55 on him on 1 bet then 55 on him on another bet etc. etc.
You can still win more than $10 000, so as long it is not in the same bet.
