The pulse pounding race to the final pit stop and US$100,000 begins with the three final teams: Sandy & Francesca, Andrew & Syeon and Joe Jer & Zabrina. Starting from the Mina A' Salam Beach in Dubai, the teams quickly learn that they will return to where it all started to get to where it all ends: Malaysia. From Kuala Lumpur, its an exciting and suspensful ride through the final detour and road block to the final pit stop in Kuching, Malaysia. There Amazing Race history is made and the winners crowned!

Four teams remain in India and luckily for Singaporeans A.D. and Fuzzie, the previous leg was a non elimination round. This means there is still a chance to be in the final three teams in the last leg of The Amazing Race Asia. However, team Singapore must come in first in this leg, or face a 30 minute penalty. In this leg's Detour, teams had to choose between Carpet and Count It. In Carpet, team had to walk to the carpet shop and find two exact carpets, using the images in the Sony Cybershot as references. In Count It team had to walk to a shop and count the dry lime and will only receive their clue once they state the correct amount to the shop owner (correct numbers were 1601, 1595, 1598 and 1577). This leg's Roadblock, one team member must zip across the canyon to the other side to receive the next clue.

There are only four Teams left, and they seem to be equally matched, judging from how closely spaced their timing is. As the Race beings its end, the teams depart for Dubai, in the United Arab Emirates. The instructions also include a significant warning: caution, yield ahead. A new destination presents a new set of challenges, and with some teams the cracks are beginning to show.

After 10 weeks of washing buses and elephants, numerous vehicular problems, dealings with chickens and fish, getting tattoos, taxi drivers who did not know the way, Yields and U-turns executed by one team… it has boiled down to the three teams, of which one who will be crowned champion. In this leg's Roadblock, one team member must locate one of seven special keys out of seventy keys buried in the sand using the metal detector to unlock the clue box. In this leg's Detour, teams have to choose between Pull or Plunge. In Pull, teams must kayak to a nearby oyster farm and find the marked shell by pulling the oyster lines, then the teams must bring the marked shell back to the beach to exchange it with their next clue. In Plunge, teams must snorkel and search for a giant clam shell with a pearl inside; the pearl should be exchanged with their next clue.

The five teams left are off again, minus Howard & Sahran who were eliminated in the last round, to Kolkata, India. The Teams were in for even more challenges this time, as they shone shoes, lighted a candle for the dearly departed, and squeezed in a giant meal. As tension between Andy and Laura and the rest of the teams emerge, the racers are greeted by a surprise from Allan as they near the end of the leg.

Mardy & Marsio, having finished last in the previous non-elimination round found themselves stripped of their money. This time, the Teams were all business as they battled to make it into the top three. The Teams began from the Margham Desert Camp, after a rest period, and as usual, left in the order that they'd arrived the previous leg. Sandy & Francesca were the first to leave, having come in first place, but were very conscious that the gap between them and the next team was only a few minutes. No new destination this time – the game was going to be played in Dubai, with new challenges. The mix of challenges included camel-riding, treasure-hunting, and an eating challenge that pushed a couple of contestants to the limit. One team said goodbye, but which one? With only three teams left, who will win the Amazing Race Asia?

The next stop on The Amazing Race Asia was beautiful Bali, Indonesia. A routine Roadblock on Kuta Beach turned into a monumental task that made some of the teams quit ... and led to the elimination of the second team from the Philippines.

As it stands, two teams have decided to bail out of the race by taking the four hour penalty for not completing a challenge. Can the other teams muster enough strength to continue with the race, or will more choose to take the easy way out? After the task at the Sony Style Store, teams received a Fast Forward option. The Fast Forward was to travel to a certain street, where there will find a clue box. The clue would then instruct them to get a permanent tattoo at Kevin's Tattoo. The Roadblock was to find a souvenir, which would later be revealed to be a small silver token that had the AXN logo on one side and The Amazing Race Asia logo on the other side in a cart of coal. In this leg's Detour the choice was between Pick or Pail. In Pick, teams had to drive themselves to a local mall and retrieve three soft toys from a game machine. In Pail, teams had to go to the Grand Tong Temple and must fill a bucket full of water and carry it to the top of the mountain where a monk will check to see if they had enough water. If they have enough they will receive their next clue.

The final race to the finish line.

No mandatory rest period this time, as the leg continues to Delhi, India. Five teams remain, with three teams still on the way to check in with host Allan Wu, at the Kolay Market. This leg the teams face dungcakes, donkeys and sacks full of chillies on The Amazing Race Asia. Tension between everyone and Andy and Laura build on the race to a yield marker. When the extended leg ends, one team will go home.

From Sydney its a short hop to Auckland, New Zealand. A new city, with new challenges, and a simple task turns into a real complication for the teams. One team finds out how easilly winning can turn into losing as they unknowingly break the rules that could cost them the race.

It is the halfway point in the race, and only half of the original 10 teams remain to claim the prize of US$100,000. In this Detour, teams had to choose between Get Fishy or Get Lucky.

This lady will hand them their final clue for the leg.

The second group of Amazing Race contestants set out on a race around the world for one hundred thousand dollars. The ten teams left the Asian Civilisations Museum near the Singapore river where they faced gruelling challenges such as a high physical task in a Detour. Teams then made their way to Manila in the Philippines where teams were required to use GPS systems to guide their Taxi drivers to the next location. Later, at the Plaza Miranda, teams had to eat eight baluts from an egg-seller's store before receiving their next clue from the egg seller. Teams then made their way to the Pit Stop located at Fort Santiago. Two teams raced each other to reach the mat first as another team was too late to catch up and stepped onto the mat last. They were relieved to know that had not been eliminated but were instead given a penalty.

The seven remaining teams started the next leg at the Auckland Museum in the centre of Auckland, New Zealand. To the South Island they go, arriving in Queenstown the extreme sport capital of the world. Teams face heights and extreme challenges in this leg.

Once again, after a mandated rest period, the Teams set off to the destination for the next leg of the race, Sydney, Australia.

From Kuala Lumpur, the Teams headed off to Jakarta, Indonesia, where they faced giant snakes and pushcarts. Mardy & Marsio slipped to second place, while the Indian Team took first place after winning the Fast Forward. We also say goodbye to the first team eliminated from The Amazing Race Asia.

Eight teams leave Auckland and continued their adventures in New Zealand as they drove to Rotorua. At the Okere Falls Scenic Reserve, teams experienced white water sledging followed by riding on a Agrojet craft through Blue Lake. A Roadblock forced team members to search the hot mud baths of Hell's Gate for their next clue.

Francesca & Sandy, nearly made an early departure from the race, but fortunately for them, this was a non-elimination round.

The Roadblock required one team member to ascend the stairs at the Batu Caves complex while carrying an offering and counting the number of steps.

If the team member did not finish the puzzle in time (which is when the diver instructor told them the time is up), the team would incur a four-hour penalty for not completing the Roadblock (which would be assessed at the pit-stop).

This lead to their elimination.

The six remaining Teams set out from Chard Farm Winery, the Pitstop from the previous leg of The Amazing Race Asia. The Teams left in the order that they arrived at the Pitstop, with the exception of Andy & Laura, who had to wait an extra 92 minutes as a penalty for Andy's speeding ticket in the last leg.
