Melbourne - The 22-yards at the MCG is considered to be one of the most competitive surfaces in the world. It offers a fine balance between bat and ball. While the bowlers get some assistance early on with mostly genuine bounce, as it gets old, the batsmen can play their strokes freely. However, generally, the spinners do not get much of a purchase at the MCG.
Sydney - Sydney is known to be a good batting wicket, with the spinners coming into the picture on days 4 and 5 of a Test match. It doesn't offer the true bounce but turns which ensures spinners have one venue in Australia to look forward to rolling their arm over.
