Speight to make Sevens Series debut
Joining Speight is lightning 24-year-old back Tom Kingston and rugged South African-born Stephan van der Walt, who are also set to make their World Series debuts at The Sevens Stadium.
Ed Jenkins will captain the side, while star centre Cameron Clark needs just 30 points to overtake Peter Miller and become Australia's all-time leading points scorer in the history of the World Sevens Series.
Pat McCutcheon (hamstring) and Nick Malouf (knee) are unavailable for the Dubai Sevens due to injury.
Australia head to Dubai on the back of some fine form having won the Central Coast Sevens last month and the Oceania Regional Olympic Qualifier in Auckland a fortnight ago. The Aussies finished as runners-up in Dubai last season, after falling to a red-hot South Africa in the Cup Final.
"Everyone is excited for Dubai. The boys did well at the event 12 months ago and there is no reason to think we can't perform well this time around.
"The team is looking sharp and the players are fit and raring to go. As a group, we are battle-hardened having played in some high-pressure tournaments. When you add the fact we have three debutants keen to make their mark, then it's a tournament for all of us – from players, coaches and fans – to look forward to," interim coach Scott Bowen said.
The Dubai Sevens is the first of 10 legs on a re-vamped calendar that now features Cape Town, Sydney, Singapore and Paris. Australia finished the 2014/15 HSBC Series in fifth position, 12 points behind fourth-placed England.
Australia have been drawn alongside Kenya, Wales and England in Pool D.
Australia Sevens squad: Henry Speight, Tom Kingston, Sam Myers, Lewis Holland, James Stannard, Con Foley, Cameron Clark, Stephan van der Walt, Ed Jenkins, Allan Fa'alava'au, Pama Fou, Tom Cusack.
