Elliott entered Monday's match with just 15 wickets to his name and a best return of 4-26 from his 10 List A matches.
But he blew that out of the water with the best-ever one-day domestic bowling display by a Victorian, with his devastating seven-wicket haul skittling Tasmania for 126 in 30.1 overs.
Tait, who took 8-43 for South Australia against Tasmania at Adelaide Oval in 2004, still holds the overall record for Australian domestic one-day cricket
But Elliott's haul ranks second, and will be remembered for years to come.

The Tigers were looking solid at 2-54 after 10 overs before Elliott sparked a collapse of 7-38.
Elliott struck with his first ball, catching the edge of Jordan Silk (7) to gift wicketkeeper Sam Harper an easy catch.
Five balls later he had Jake Weatherald (31) caught behind, with Harper forced to dive this time to complete the dismissal.
Matthew Wade (8) was Elliott's third victim when he was caught at point.
Jake Doran (1), Beau Webster (14), Tom Rogers (1) and Bradley Hope (14) all succumbed to Elliott as well as Tasmania crashed to 9-92 in the 23rd over.
Elliott had the remarkable figures of 7-8 off 6.2 overs at that stage.
One more scalp would have given Elliott the overall record for Australian one-day domestic cricket, but he wasn't able to dislodge tail-enders Gabe Bell (17) or Matt Kuhnemann (17no) with his next 10 deliveries.
Elliott was surprisingly pulled from the attack following his eighth over.
Bell and Kuhnemann put on 34 runs for the final wicket before evergreen veteran Peter Siddle (2-26) found the edge of Bell to end Tasmania's innings.
That marked Harper's sixth catch of the innings, but the day was all about Elliott as he was clapped off the field.
Another memorable moment from Monday's match was a heart-in-the-mouth juggling catch from skipper Will Sutherland at slip to remove Mitchell Owen in the first over.
Sutherland juggled the catch three times before holding on.
How about this to start the summer? A screamer in the slips from the skipper if you don't mind! — cricket.com.au (@cricketcomau) #OneDayCup pic.twitter.com/P0zeKZk0bfSeptember 23, 2024
