Embattled Smith and Australia are under pressure following Saturday's stunning capitulation in Hobart after they were bowled out for just 85 on day one of the second Test against South Africa.
Smith's name has been thrown under the spotlight amid calls for wholesale changes after Australia's 177-run defeat in the opening Test, with the Aussies now staring at a fifth consecutive defeat.
But Sutherland insists the 27-year-old Smith, who finished 48 not out as his team were skittled, is the right man to lead Australia.
