You sound like a pretty good tipster, Chief. I agree with you that the outsiders Race 6 County Tyrone and Race 7 Diamond Dane are good chances, especially Diamond Dane.
My Brisbane tips are as follows:
Race
1) Palaris
2) Tahitian Star
3) Vladivostok
4) Sundial
5) Altiero
6) County Tyrone
7) Diamond Dane

Madison
I will stand out the above in a quinella with the field for 50c.
In two big races, I will also do as follows:
Derby: box trifecta 1,8,18 (2,16&17 are also good chances)
Stradbroke: Box exacta 1,4,6,17 also Quinella 15,16/1,4,6,15,16,17
Also best $100/1 shot - Princess Clang
Hopefully, I won't be broke at the end of the day! It is a big day after all!
PS: Chief - I hope you don't mind that I have put my tips on the end of yours!
