Rahul was decisive with his shot selection, pulling short balls in his range, both along the ground and over the in-field, as required.
Jaiswal was resolute in his defence, but brought out his natural flair occaisonally. His slog over backward square leg off Starc being one of the several highlights of his knock.
Known for his attacking game, Jaiswal left the ball well, especially when it was directed at his head.
The 22-year-old youngster wasn't afraid to take on the quickest Australian bowler and a veteran of 90 Tests. Jaiswal even told him that he was "too slow" at one point.
The duo negotiated the second session of day two safely, scoring 84 in 26 overs after the previous four sessions had seen 20 wickets fall.
Jaiswal was always keen on taking on Lyon, often stepping out too early. He was, however, good enough to adjust even when Lyon changed his line and length.
Jaiswal brought up his fifty in 123 balls soon after Tea on Day two. His muted celebration showed he was in it for the long haul.
The solidity of Rahul and Jaiswal in the middle meant India's No.3 and 4 were in a jovial mood in the dugout while waiting for their turn to bat.
The Australian captain, on the other hand, had stress written all over his face as Rahul and Jaiswal went about creating history and grinding Cummins' troops in the dirt.
The pair did present a couple of chances, with Rahul taking off for a suicidal run late on the second day. But Steve Smith's throw was so far off that Lyon couldn't gather it cleanly enough to take the bails off. Rahul was on Rahul was on 42 then.
Rahul reached his first Test fifty as an opener in nearly three years, having shuffled around the order in the meantime.
As the light started to fade on the second evening, Starc made one final burst, trying to bounce out Jaiswal. The left-hander hopped and fended, and eventually survived even with Travis Head lurking at short leg.
After the first two innings saw scores of 150 and 104, Jaiswal and Rahul added 172 on their own by the end of day two, a turnaround almost reminiscent of the famous Laxman-Dravid partnership in Kolkata.
With the track getting easier and easier to bat on, the pair walked out on Day three, chasing the Indian record for the highest opening partnership in Australia.
Rahul carried on his momentum from the second evening, playing two crisp cover drives in the second over of the third day off Mitchell Starc. The signs were ominous for Australia.
Batting on 95, Jaiswal chose the most extraordinary way to reach three figures, upper cutting Josh Hazlewood over fine leg for a maximum.
Arms aloft, eyes to the heavens - this has already become a trademark Jaiswal celebration in such a young career. They are calling him the New King in Australia. Perhaps they might be on to something.
Soon after crossing 200, Starc finally got Rahul to commit an error as the opener edged one behind to the wicketkeeper. The marathon partnership, lasting 378 deliveries and costing 201 runs was finally broken, but not before breaking the spirits of the Australian bowlers three days into the Test summer.
