Garmin-Barracuda director Allan Peiper says that with the 45 riders separated by a matter of seconds, the opportunity for a less-heralded rider to come out of the wood work on the queen stage up Willunga Hill should not be dismissed.
"Everyone thinks it’s going to be the favourites and Gerrans is obviously ‘the favourite’ being national champion, but there are a lot of riders who haven't been talked about," Peiper said to Cyclingnews in Tanunda at the end of stage 4.
Machado first showed himself on stage two when he picked up third place on the climb at Lenswood, the first available place after the day's break of two riders. The RadioShack-Nissan rider has shown himself to be one of the best talents to come out of Portugal since Jose Azevedo, already holding a handful of national championships, and recently developing a taste for shorter stage races.
RadioShack-Nissan's presence on the front today was very much to make the race harder for the 26-year-old, but it's Willunga where he can really excel.
Sicard meanwhile is a former under 23 world champion, and has previously beaten the likes of Alberto Contador on a hill-top finish in the Criterium du Dauphine.
They are just two of a handful of riders, including Linus Gerdemann, Ryder Hesjedal, Sandy Casar, Sergio Paulinho and Wilco Keldermann who have so far avoided the spotlight.
"I’ve not gone ‘full bore’ yet," echoed Michael Rogers in Tanunda. "But that’s the same for a lot of guys. Valverde, and some others haven’t even touched the pedals yet. I think we could see some surprises tomorrow."
