Wallaby line-out to be fixed for Boks
The Wallaby lock expressed his dissatisfaction at the Wallabies' line-out, which has come under increased scrutiny in recent weeks.
Their next big Test come in the Rugby Championship Round Three encounter in Brisbane on September 10.
Mumm has been one of the most consistent performers in the line-out since the Rugby Championship started, with a perfect record in the set piece.
However, in two Rugby Championship Tests this year the Australian line-out has managed just a 69.23 percent success rate.
The statistic puts them last among the Rugby Championship teams – with New Zealand at 100 percent on their own throws, Argentina enjoying 91.67 percent success rate and South Africa at 91.3 percent.
Not surprising then the Wallaby line-out has been put under the microscope.
However, the 32-year-old said he felt the Wallabies' line-out woes were not unsolvable.
"If it's the elephant in the room it's a pretty big one," Mumm said in an interview on rugby.com.au.
"We've changed the way we've been doing line-outs and I think there's an element of you need to congratulate the All Blacks line-out defence.
"It's something they've improved at and we've got to improve our attacking ability to counteract it.
"Our line-out's not good enough, certainly we need to get better at it, there's no way you can shy away from that.
"If you want to be one of the great teams in the world you've got to be winning a very high percentage of your line-out ball.
"We don't shy away from the fact our line-out needs to improve. I feel like we're in a spot of good work ethic. I feel like we've got the right people around us."
Mumm was quick to heap praise on the All Blacks as much as acknowledge his own team's woes, after the disruption that Brodie Retallick, Sam Whitelock and Kieran Read caused at the line-out.
"It's certainly we need to get better at it, there's no way you can shy away from that," Mumm said.
"A couple of years ago it wasn't a strength for New Zealand and it's something they've worked really hard on.
"I think the key for us at the moment is to try and sort it out as a group and keep it – it's a pretty competitive environment in the way the combinations have been changing.
"I think that will benefit us in the long-term but in terms of who gets selected, it's not up to us."
