Brazil W vs Australia W (Asian Handicap) prediction

I really do not understand these odds! Brazil is a good team, but nothing much above average and they rely heavily on specific players like Marta for example. Cristiane, main scoring team this injured and Debinha to replace. Debinha is a very fast player, but technically inferior that Cristiane. Australia is a decent team and have offensive characteristics, always have tough games conra Brazil, including eliminating Brazil in major tournaments recently. The only advantage to Brazil is playing at home, teams are semehantes the technical level, and I think if the Brazilian goal take to happen, can cause some anxiety and nervousness in the team. Australia has players who may have advantages in this type of situation. And even if something happens goal for Brazil, I don't think though they can get the rest of the game without conceding goals against Australia. I believe in a very difficult game, very equal and with slightly advantage for Australia that is not too pressed for classification as Brazil is pressed to Qualify I would not be surprised if Australia can win the game, or at least tie the game in regulation time.
