KEY POINTS:
Dual rugby international Andrew Walker was yesterday named in an Australian squad for next week's International Rugby Board sevens world series tournament in Hong Kong.
Walker, who played seven tests and now plays for Queensland Reds in the Super 14, joins fellow-Reds winger Caleb Brown in the Australian squad, also chosen for the April 5-6 Adelaide leg.
Shawn Mackay will again captain the team and is joined by experienced sevens trio Damon Murphy, Luke Inman and James Lew.
