I think the season will go like this:
Leg 1: Sydney to Manila, Philippines: NEL
Leg 2: Manila to Legazpi City, Philippines: Kym & Donna eliminated
Leg 3: Philippines to Dehli, India: Adam & Dane eliminated
Leg 4: Dehli to Dubai, UAE: Sue & Teresa eliminated
Leg 5: Dubai to Istanbul, Turkey: Ross & Tarryn eliminated
Leg 6: Istanbul to Paris, France: either NEL or Geoff/Sticky & Sam eliminated
Leg 7: Paris to Havana, Cuba: either NEL or Geoff/Sticky & Sam eliminated
Leg 8: Havana to Vancouver, Canada: James & Sarah eliminated
Leg 9: Vancouver to Banff, Canada: Shane & Andrew eliminated
Leg 10: Banff to Beijing, China: NEL
Leg 11: Somewhere in China?: Michelle & Jo eliminated
Leg 12: China to Fraser Island, Queensland: I really hope either Joseph & Grace or Emilia & Lucy win over Steve & Paul if they are my predicted F3. Although of course the top 5 are interchangeable.
