The Bahrain rescheduling chaos means Mark Webber might have to miss his own adventure challenge later this year.
The Tasmanian event is returning in December for the first time since the Red Bull driver broke his leg at the end of 2008.
It was scheduled for December 7-11, after the end of the current season, but the FIA is now proposing to extend the calendar until mid December to make room for the controversial Bahrain reshuffle.
If that happens, 34-year-old Webber would miss out.
"There is still a level of uncertainty about how the F1 calendar will end up so we are just sitting back and watching like so many others as to how it will all unfold," event organiser Octagon's chief Mark Perry told the Tasmanian newspaper The Mercury.
"Once we know the facts we will then consider our options," he added.
Webber has been easily the most outspoken driver on the issue of the Bahrain rescheduling, admitting he thinks the 2011 race will ultimately succumb to the political and logistic issues.
"Even though a decision has been made, I'll be highly surprised if it goes ahead this year," he said.
"I hope F1 is able to return to Bahrain eventually but now isn't the right time."
