It seems to me that unless we're all wrong about the number of episodes, then thiere was not an uberleg. But two legs, with no rest period between pitstops. That is a new wrinkle, but one that's been developing the last few seasons as the show has dropped all references to the 12-hour rest period at pit stops.
Phil described the race as having 12 legs.
He described the winner of the express pass as the first to arive at the first pit stop, which did happen in this leg.
He described the beach location as a "pit stop" greeted the first ten teams as X to arrive" and the clue directing teams there warned that the last team to arrive "may" be eliminated.
So what we have is a regular first leg (with just a roadblock and no detour.
Conclusion: There is no uberleg this season, although WRP did a good job in emulating an uberleg in Sydney.
I agree with the thrust of theschnauzers' comments. However, if there was no pit stop time lag, why did teams not get on the 620pm flight to Broken Hill? Also, why was there a greeter? Typically if there is a greeter then it's not a TBC. Phil promised surprises, so I guess having a TBC with a greeter is something new. I believe that teams find a HOH that works effectively like a pit stop.
The times of the flights the next day to Broken Hill may have been set so as to assure that all teams completed the first leg and could be gathered for making the charter flights to Broken Hill. It might have had to do with daylight flying conditions (in the US that's known as VFR flight rules) or that the additional aircraft needed for the teams and crews weren't going to be available and in position until that next day. Or they may have not planned to have teams in Broken Hill until the next morning.
From what I recall from the live sightings, the teams gathered at Town Hall (IIRC), and signed in there for the flights. We do know Jet/Cord lagged behind the other teams getting to that spot (after sunset?) and I suspect that didn't cause the next morning flights, but that WRP planned for having a later time for teams to complete the first leg than was actually needed.
We'll know for sure, I suppose, once we hear what Phil tells the Cowboys at Shelly Beach. But for the moment, I think we're dealing with two legs and a no length pit stop rest period.
