Vice-captain Shane Watson has refused to be drawn on the likely bowling line-up Australia will take into the first test in Cape Town this week.
There are five fast bowlers in the squad but it seems Mitchell Johnson (nine wickets for 112 in a tour game), Ryan Harris and Peter Siddle are the favourites to form a three-pronged attack with Nathan Lyon as the spinner. However, the slower conditions at Newlands may keep stump-to-stump bowler Trent Copeland in the frame.
The 25-year-old took only one wicket in Australia's win over South Africa A but he performed well in Sri Lanka and could be viewed as a nice balance for the explosive approach of Johnson. Back in 2006, another medium-pacer, Stuart Clark, took nine wickets in Cape Town on his test debut for Australia and Copeland would view Newlands as his best-suited deck in South Africa.
Fast youngster Pat Cummins is also in the mix but his chance is more likely to come if Australia feel a change is required for the second test on the bouncier wicket at The Wanderers, Johannesburg.
Harris is a certainty, despite being rested from the tour match, but fitness concerns remain an ongoing issue for him. Siddle was impressive with overall figures of five for 92 in Potchefstroom and is a deserved favourite.
