The Ocho, the only reason I can think of applying the $30 minimum is that if an outsider is layed and successful, then the profit is very low and the commission Betfair receives is even lower..and unacceptable to them. However, that's only my assumption.

Out of interest I'll list today's selections:

Port Macquarie
1/10
2/3
3/3
6/6
7/5

Bairnsdale
8/5

Townsville
3/9
6/8
7/6
