To speed up the process of qualifying for a region, all you have to do is use 2 controllers. Make sure you are Controller 1, move to the opposing team and move Controller 2 over to your team. Then, all you have to do is FORFEIT the match with Controller 1 and keep on doing it as your team will get a default win of 3:0 and in the end will qualify for the World Cup, gaining all points. To forfeit a match, press when you're in-game and select the option "Forfeit Match" at the bottom of the menu.
For this achievement, you'll have to start another "2010 FIFA World Cup" campaign, and make sure to set the tournament type to "Qualification", so you only play the qualification for the World Cup.
Make sure to set the region to Oceania, select your team pressing , then press to advance and simply try to win all matches.
The qualification requirements for the region of Oceania are as follows:
Qualification in Oceania is composed of two rounds. After the first round, the top 3 teams advance to a final round group stage with New Zealand.
The winner of the final group stage will then play against the winner of the playoff between the two 3rd-placed Asian sides for a spot in the finals.
NOTE: Use the 2-controller method mentioned above to make sure you finish first and qualify for the World Cup.
