Scrum coach Mario Ledesma has had a positive effect on the Australian forwards, as prop Scott Sio reveals.
The Argentine powerhouse was picked up by the Waratahs at the start of the Super Rugby season, working under then coach Michael Cheika.
After earning his stripes, Australian head coach Cheika called him up to the big leagues, where he is having a great impact on the players.
"There’s no huge secret with Mario," revealed Sio.
"One of his biggest things is consistency and it's not just on game day, it's during the week, how we go about training and band together.
"Realising the importance of one to eight in the scrum has been huge for us and knowing that we're going to get the most out of each other has been great so far.
"As he always says of the scrum, 'You're only as good as your last one' so we've got another big test this week. I'm sure he'll have some points for us to work on this week."
Sio added that Ledesma has brought new life into Australia's scrum sessions and it is showing on the field.
"He's tough at training but he's very passionate about what he does and it really rubs off onto everyone," continued Sio.
"And everyone really enjoys coming in for scrum sessions. In the past, people looked at scrums and thought, 'Awww, scrum sessions' but we really enjoy it now. He's brought a great vibe to the unit session as a whole and everyone's buying into it.
"Having different characters in a group like this is great. It brings a different sort of flavour to the group. I think Mario's been great, he's been a pleasure to work with and the guys have a lot of respect for him and the philosophy he’s trying to bring to the group."
