Australia squad trimmed to 27
Head coach Ange Postecoglou confirmed on Tuesday the trio will not be on the plane to Brazil, with centre-back Good ruled out through injury and the tournament deemed too soon for Sarota in his comeback from a knee reconstruction.
Youngster Brillante was not expected to travel, having been named in the expanded 30-man group to give him experience of an elite level training camp.
"It's not the best news to deliver," Postecoglou told a press conference in Sydney.
"To the credit of the three players they've taken it professionally.
"Disappointing for those boys. A couple of decisions mainly because of their bodies not being to hold up."
Australia, who played out a lacklustre 1-1 draw with South Africa at ANZ Stadium on Monday, depart for Brazil on Wednesday.
A further cut from 27 players to a final 23 is expected on June 2.
