How to Help Australia to Win the 4th Test

I must admit, I thought that by splashing out some money on England to win the 3rd Test, when they were being offered at ridiculous odds of $5.50, was a sure way to ensure victory for Australia. I was found to be incorrect in this case, but I won't lie that the extra cash windfall helped ease the pain slightly.

So how to help Australia in the all important 4th Test? Well, we really must win, we can't hope to draw and then win the 5th Test, so I need to take out both the option of England winning or salvaging a draw.
Thankfully the bookies are working for me in this instance, and so this is what I have done.

I have taken England at $3.40 to win the Test - $30 @ $3.40 = $102.00
I have also taken the draw at $3.75 - $20 @ $3.75 = $75.00

So for my $50 outlay, I will either:

1. Take home $52 if England wins Test
2. Take home $25 if it is a draw
3. Lose $50 - but Australia win Test.

Surely there is no losing scenario there?And obviously the gambling gods will not allow me to win money on two consecutive cricket Tests, so it's a given that Australia will win.

Perfectly logical...
