While France is the big favorite in its game vs Australia, there is no such thing as free money and thinking that is a 100% winning bet. Surprises always happen at world cups and not saying that Australia will win, but always be cautious also.
Yes, the problem is to find the balance between "sure bet" and "high odds". Similar situation we had many times with F1.
Now, we may take for example England (1.26) - Iran (12.04). And 4.55 for draw. I do not think 1.2 is worth risk.
