It is most possibly one of two species of gall rust given it is on a bipinnate Acacia. Uromycladium murphyi is known to occur on Acacia dealbata, A. decurrens, A. elata, A. mearnsii, A. penninervis and A. rubida. several of these species have bipinnate foliage. Endoraecium carnegiei is known to occur on Acacia dealbata. The specimen may not yet to be mature enough for diagnostic spore production to have occurred, I've had this trouble before with specimens that looked like this.
