"I'm confident that we can give all four of these games a good go. I think we owe New Zealand one certainly," said 25 year-old Jones.
"We have got nothing to fear. Over the recent weeks in Europe the Welsh regions have proved that. As individuals and teams, we have grown up and matured and learned the importance of fronting up.
"It's a case of not being afraid, because if we get a good platform up front we have some of the best backs in the world.
"The only thing that's going to kill us is us. We have got to make sure we don't go in to our shell. We have got to go out there and put a show on."
For eight-times capped Jones to make the team against Australia will be the end of 18 months of injury heartache.
He was called into the Lions tour of New Zealand two summers ago but he has not played for Wales since they secured the Six Nations Championship Grand Slam in 2005.
A serious shoulder injury has seen him sidelined almost entirely since returning from New Zealand.
"It just puts an end to what has been a nightmare for all of last year. It's time to move on and try to pick up where I left off," added Jones.
"There's nothing better than playing these games in front of a packed Millennium Stadium and that's the only thing that really kept me going, getting back involved and be a part of World Cup year.
"Playing again seemed a long way away when I couldn't move my arm and had to put a sling every morning.
"I'm looking forward to Saturday because I have been off the international scene longer than I was in it.
"It's been 18 months since I played so it's going to be a massive challenge for me and with Johnno (Australia attack coach Scott Johnson) coming back it's going to spice it up a bit.
"It's a fantastic fixture and these are the days you look forward to."
