I think Hilfenhaus is improving very quickly, and we'll see him in Australian colours soon enough. In fact, I'd have him infront of BOTH Johnson and Tait for the test team. However, he wasn't really setting the domestic comp on fire last year, in the shorter form of the game anyway, but he's come a long way since then and Australia has high hopes for him. The reason Tait is in the World Cup team is because, in the 50 over game, he's had 4 consecutive years averaging less than 22 with the ball. With a list-A record of 42 matches, 76 wickets at an average of 23, he could no longer be denied a spot in the national team.
