I was just browsing the Bookmaker Reviews at this site:

http://www.aussportsbetting.com/bett...maker-reviews/

Although I do not know how up-to-date their reviews are (not dated) it is interesting to see the Daily Win limit for different Bookmakers
I don't think any of them would have paid out on TC's example above because eg.

Topbetta only has a limit of $20k daily win limit and even Sportsbet would seem to only have a $500k daily win limit (I have never troubled any bookmaker on their limits LOL)
