The draw in Bahia could toss Australia into a group alongside host and five-time champion Brazil, France and old sporting adversary England.
Alternatively, it could place Ange Postecoglou’s men in a less daunting group alongside Switzerland, Cameroon and Russia – with many permutations in between.
The FIFA 2014 World Cup Draw explained
Whatever the outcome, Leckie - who led the line in the November 1-0 win over Costa Rica in Sydney - is convinced there will be no repeats of October’s six-nil losses against France and Brazil.
"In some ways you want to play the supposedly weaker nations and in another way you want to face the best," Leckie said.
"The bottom line is they are all there for a reason and they are all going to pose a big challenge.
"Of course, playing the likes of Italy or England would be great but really I don’t have a preference.
"The most important thing is we showed against Costa Rica that we really can actually play football, which maybe some people doubted after those big losses against Brazil and France."
The 22year-old, who returned to club action for 2.Bundesliga club FSV Frankfurt at the weekend after a two-week injury absence, said: "I think the boss has the belief that some of the Australian public had lost faith in the ability of the national team - and he is all about rebuilding that faith.
´The signs were good against Costa Rica. Ange wants us to achieve great things for the national team and he is about us making history as nation. He is up there with the level of European coaches.
"Some of the meetings we have had and the speeches he made were an eye-opener and he has given the squad great belief and motivation."
Lively and enterprising against Costa Rica in what was his first full start, and fifth cap for his country, Leckie’s performance was a statement of intent and pleased his new boss.
"I think he was happy with me and I thought I did well enough," Leckie said.
"Ange wanted to have a look at some of the younger players and I enjoyed the experience.
"It was a privilege to start for the national tram and I thought we played some really nice football.
"I had a great chance to score just a few moments after coming back on after receiving treatment on my knee and I was disappointed that I didn’t take it.
"But overall, I thought I was involved and made an impression on the game."
Leckie is also encouraged by the slick passing style sought by Postecoglou and believes Australia could turn some heads in Brazil.
"There may be some fans out there at the moment that believe we will really struggle when we face the best teams and basically have no chance," he said.
"But hopefully we will surprise them by the brand of football we play and by showing we can keep the ball and compete with the best. I think it will surprise a lot of people.
"The mentality under Ange is great, even when we lost possession against Costa Rica the pressure we put on to get the ball back was excellent.
"That has been drilled into us by Ange and hopefully - when we come up against the bigger nations - we can have success with the same tactics.
"We don’t believe we are too far away from giving those bigger teams some real tests at the World Cup.
"When you look at the performances against Brazil and France there probably wasn’t too much football played by us, but Ange is drilling into us to play with confidence.
"At training it’s all about possession work in tight areas. I can see the change from a few months ago in camps to now - and it’s all positive."
