Conondale returns to the calendar as the first of 10 rounds to be contested during the season, which is tipped to be the most competitive on record with an all-star line-up of national and international contenders.
Defending champion Jay Marmont will vie for a fifth straight MX1 (Pro Open) title after switching to Monster Energy Kawasaki during the off-season.
"We've done a lot of testing and we've been working hard, just getting seat time and testing on the 2012 KX450F," 28-year-old Wollongong resident Marmont said. "The whole package has come together at the right time, but I'm under no illusions and I'm certain that it's going to be tough.
"Last year I got the championship at the last round, but I haven't left anything on the table this year and I've been putting in more work than ever. This is just what I need to keep me going at the moment and I am excited to race everybody out there for this number one plate."
Other top Australian riders include a host of rising stars who are highly capable of winning races and fighting for the title, including Lawson Bopping (CDR Yamaha), Todd Waters (Motul Pirelli Suzuki), Tye Simmonds (Honda/Red Bull/Simmonds Racing) and Jake Moss (Campbell Mining/TLD/Maxima Honda).
Former national champion Dan Reardon will also be another rider in with a chance at lifting the crown, the Brisbane-based 26-year-old spearheading JDR/KTM Factory Racing's hopes as their lone MX1 contender in season 2012.
"The team structure is great right now, we've been really productive during testing and everything like that," Reardon commented. "I've been real happy with the way things are going this year so far and it feels good to be healthy heading into the season."
No less than 20 world class riders have signed up for the season opener throughout all three national championship classes - MX1, MX2 and MXD - and making for a truly international series on Australian soil.
Former Motocross World Champion Ben Townley will enter the weekend as a red-hot favourite in an anticipated one-off appearance for Carlton Dry Honda Thor Racing, recently signed to compete in the United States for Chad Reed's TwoTwo Motorsports Honda team following the Conondale round.
"I want to use my race craft going into [the AMA season], so at least round one is on the cards for me," recently crowned New Zealand Motocross Champion Townley added. "I'd like to repay the fans and everybody involved in Australian motocross, so it will be nice to see people face to face before I head off."
Last year's series runner-up Josh Coppins (CDR Yamaha) returns to the MX Nationals from New Zealand, as does fellow Kiwi Cody Cooper (Motul Pirelli Suzuki) and Scotland's Billy Mackenzie (Monster Energy Kawasaki). In addition, dual British champion Brad Anderson (Carlton Dry Honda Thor Racing) joins the fray for a full-season after winning a round as a wild card in 2010.
Sweden will be represented by 20-year-old rookie Calle Aspegren on a privateer Honda, heading to Australia after spending a full season in the U.S. during 2011.
The 250cc MX2 category also has an international flavour, with a new champion set to be crowned since current champion Matt Moss is now based in America flying the Aussie flag for JDR Motorsports and KTM.
JDR/KTM Factory Racing will feature a three-rider Lites team consisting of former champion Ryan Marmont, Josh Cachia and Queensland's Brenden Harrison when he returns from a leg injury. The team will shoot for a third straight title in the 250s.
Dual runner-up Kirk Gibbs returns for Serco Yamaha Metal Mulisha Racing alongside new teammate Luke Styke, while Carlton Dry Honda Thor Racing has signed former Serco rider Ford Dale in a single-rider MX2 assault. Monster Energy Kawasaki has ever-popular Victorian Kade Mosig in its corner.
Motul Pirelli Suzuki has opted to go the international route, signing British talent Steven Clarke. However, while he continues to recover from injuries sustained last year, New Zealand Suzuki regular Scott Columb will sub for Clarke at Conondale.
Australia's top development riders will also be in action all season long in the MXD (Under 19s) category. This is the class where riders sharpen their skills before stepping into the pro ranks, as we'll see in 2012 with current MXD champion Errol Willis joining the MX2 class for Raceline Pirelli Suzuki.
