If the Pakistan team can play with Australia with the same consistency as they batted against Sri Lanka and they got a great win then it will not be impossible to win the match with Australia. But Pakistan team sometimes play very bad due to which they have to lose like against India they did not play very well India won very strongly. In today's match, Australia will want to beat Pakistan to add their points, undoubtedly Australia is a good team, but the cricket players of Australia are not able to present themselves in this way in this World Cup.
Pakistan's team is very unpredictable. They will surprise Australia or their fans

in this match. Pakistan's team is in very good touch, and their middle order is scoring runs (except in the match against India). Australians are getting some form back, but still, Smith and Warner are not in good touch. Pakistan often choked against Australia because of their pressure.
It is a do-or-die game for Australia; if they lose today's match, they will be out of the competition. They have to win all of their remaining matches to stay in the tournament, and those matches are against in-form teams. Australia will try to win this game with a margin to improve their run rate, while Pakistan will try to just win this game to stay alive in the tournament.
