In Sydney to watch the final of the 2015 Asian Cup between the Socceroos and Korea Republic, Blatter repeated comments he made in his FIFA Weekly column that Australia deserves to host the football showpiece.
"I am convinced that Australia could and should organise the World Cup but it was not easy, they were candidates for the 2022 World Cup but the opposition was a very big opposition and they passed at the last place.
"This should not mean that they should not come back and try again because if you never take a risk you will never have a chance, but if you take a risk you also have a chance to lose."
The 78 year-old, who is campaigning for a fifth term at the helm of football's governing body, admitted FIFA had learned some valuable lessons from the controversy-tinged process of voting for two World Cups - 2018 and 2022 - in one sitting.
"The 2nd of December 2010, I will never forget this date where we have made the decision for two World Cups, which was wrong," Blatter said. "We have also taken the decision later on that it will be the congress that will elect the designated World Cup organiser and the list of requirements.
"I will tell you, that human rights and other rights will be part of the basic conditions to organise the competition. That will be new for the next World Cup in this new approach – the world cup 2026."
On his own legacy, Blatter spoke of the unfinished busniess driving him on to another term as president.
"I need this new term to finish my mission and to prepare also a succession that we have for 2019. If ever I am re-elected that we have a clear and clean situation."
