Key has some big shoes to fill, having come in for Graham Thorpe after the squad was initially named.
There's been criticism of the selectors plumping for "another opener" but he is a strong insurance policy if there are problems at the top of the order.
And after a low key start to his career in the summer, a place down the order may be just what he needs.
The show of faith will help his confidence and he knows Aussie pitches, having been Down Under last summer with the Academy.
