The 29-year-old's impressive fortnight in Melbourne - capped off with his first grand slam title alongside Rinky Hijikata in the men's doubles - boosted his career earnings by more than half-a-million dollars.
Kubler also reached the second round of the men's singles - a career-best at his home slam - and the quarter-finals in the mixed doubles with Maddison Inglis.
The results earned Kubler $518,975 in prize money over the two weeks in Melbourne, including a share in the massive $695,000 men's doubles prize cheque.
The total has set Kubler up to surpass the $625,437 he earned throughout the 2022 season, which peaked when he reached the singles fourth round at Wimbledon.
A former junior world No.1 and current men's world No.84, Kubler had earned a total of $1.25 million from his injury-hit career before this year - meaning he has almost trebled his on-court earnings in the past 12 months alone.
He is now better placed than ever to taste more success, building from a stronger financial footing.
"For me, it makes a massive difference," Kubler said of his latest windfall.
"Winning grand slams, singles especially, but doubles also, I would almost say to an extent (it is) a career-changing thing.
"I feel after this I can really almost choose who I want to come (on tour) and when I want them to come, which is pretty cool."
Kubler works with Jarrad Bunt on the Gold Coast and will comfortably be able to take his coach overseas when the time is right.
"That gives us great flexibility with our schedules, great peace of mind," Kubler said.
"We're not worrying about making ends meet.
"Even if we're homesick a little bit, we can bring our family over or we can bring whoever over.
"It makes it a lot more easy, a lot more comfortable for us."
Kubler and 21-year-old Hijikata had never played together before the Australian Open but are now eyeing further doubles success.
The wildcard pairing upset three top-10 seeds in Melbourne before beating Monaco's Hugo Nys and Poland's Jan Zielinski 6-4 7-6 (7-4) in Saturday night's decider.
Kubler intends to head home to recuperate after his Open triumph, while Hijikata travels to Tasmania for the low-level Burnie International, where he plays his first match on Tuesday.
