Rated a strong chance to fight with the international stars for victory, Hollis did just that, topping the timesheets after each day and battling through a tough motocross final to take the trophy with a 32-second lead over the next placing.
"I am really stoked, winning the four day is a huge honor and I am also proud to have won it for Australia. . .," Hollis said.
"I just kept giving it everything and knew that a good buffer back to second and third would really help me come today's motocross event."
Runner-up in 2007, Hollis' pre-season training paid dividends, the 23-year old able to bounce back strongly after an average of over 7 hours on the bike per day.
Riding for the Ballard's Yamaha Off Road team, Hollis is the first Australian rider to win the title since Glenn Kearney in 2004.
