It's both generally accepted and correct that there are only 4 "must-win" events for any GOAT contender: the four majors.
Having said that, 2 of the four are on hard courts, the AO and the USO, which means that a player can show prowess and even all-time greatness on hard courts without winning both hard court majors. Showing prowess on all surfaces is one of the reason why winning different majors is such a big deal.
Given the greater current and historical prestige of the USO as compared to the AO, could a hypothetical player be the GOAT without winning the AO? Consider a hypothetical player with Roger Federer's exact resume, except instead of having a 6-1-8-5 Major title breakdown, he has SEVEN of each of RG, W, and USO, for 21 total Majors, but zero Australian Opens. GOAT? If not, why not? What would the AO title prove? Would it change your mind if the hypothetical player won EIGHT of each of RG, W and USO for 24 total Majors? Would the lack of an AO title really hold that player back from GOAThood?
Honestly, it'd be hard to call that hypothetical player anything other than the GOAT, as you couldn't make any meaningful surface criticisms of him.
