Australia improving under Rennie's measured approach, says defence coach

Australia defence coach Matt Taylor said head coach Dave Rennie's clarity and calm demeanour were key factors in their improvement over the last couple of years and that the Wallabies were now more adaptable as situations change on the field.

Rennie, who replaced Michael Cheika after the 2019 Rugby World Cup, led the Wallabies to their first win over England in nine matches in Perth on Saturday despite playing much of the game with 14 men following Darcy Swain's red card.

Even-keeled Rennie gave the squad the stability it needed, said Taylor.

"He's very measured, he doesn't get too high, he doesn't get too low," he added.

"He takes things as it comes, so I certainly think that the osmosis of him being very calm probably promotes through the group.

"He's also very good at the clarity within the team. The fruit of that over the last couple of years maybe came out at the weekend, where we were able to adapt and adjust and get on with it without too much panic at all."

Australia won the first test 30-28, with England only putting a touch of respectability to the scoreline through late tries from Henry Arundell and Jack van Poortvliet.

"I think those two tries show that England have really good individuals and if you're not 100 per cent zoned into your systems or you don't execute your tackle you can come unstuck," said Taylor.

"It was really disappointing that we conceded those tries but it just goes to show a test match is maybe 82, 83 minutes.

"It's a really good reminder for us without the loss."

The second of three tests takes place on Saturday at Brisbane's Lang Park, where Australia have won their last 10 matches.
