Towering Wallabies lock Will Skelton is working overtime to improve his lineout jumping ahead of next month's Rugby World Cup.
The big-hitting Skelton knows the set-piece, as ever, will be crucial in the UK and it's an area he is desperate to better in.
"I think I can be a quality jumper and really bring that skill for my teammates," said Skelton.
"I'm working very hard with my fellow locks and the coaching staff on that."
Skelton, who is 204cm and about 145kg, is one of four specialist locks in a squad that boasts a couple of excellent lineout technicians in Rob Simmons and Dean Mumm.
