What a match! Aussie qualifier 22 y/o Dane Sweeny, pushed it to a 5th set, 3 hours! Sadly been broken in this deciding set, fingers crossed

update
A tough day for Australians, with wildcard Walton falling to higher ranked Arnaldi in straight sets at the fairly new Kia Arena this morning, while walkover qualifier Sweeny agonisingly lost in a 5 set nearly 3.5hr epic to a far better seeded opponent on JCA this arvo.
Australian Chris O’Connell (who is a better player than both the aforementioned Aussies) is currently on 1573 Arena, after losing the first set 3-6 is in a close battle in the 2nd, best of luck. He progressed to R3 IIRC at the AO a couple of years ago.
I will say it’s been nice not having any high seeded/ranked Australians expected to do well, as well as other big names on the new Sunday D1, far more relaxing and enjoyable for fans, if that makes sense, compared to the usual clusterfu*k of the old Monday D1, which could get convoluted and rather stressful!
update 2
Aussie Chris O’Connell won his R1 clash that stretched nearly 4.5 hours, an instant classic 5 set encounter.
Magda Linette was forced to retire injured in her match with former champion Caroline Wozniacki back, after the former also lost the first set. The second retirement today. Bringing forward Frances Tiafoe’s match, in some unexpectedly good news (with delays looming after the amount of long matches today depsite organisers’ wishes adding this extra day).
Meanwhile, at the time of writing this, Fritz and Acosta are locked in yet another 5th set and 4 hour epic.
And Australian Kubler is fighting Galan, after 1 set each, they’re now in a tense tie break.
