A combination of a convoluted points system and a two-and-a-half hour time difference meant South Australia were subjected to a nervous wait before learning their finals fate as they sat glued to the live stream in Perth.
But a five-wicket haul to Ash Turner ensured the result was worth waiting for, setting up a re-match of last year's final against ladder leaders Victoria.
"The game in Perth was the one that really counted and we watched four or five hours of ball-by-ball in a pub somewhere in Hobart as a group," said Siddons.
"Quite a few blokes walked away from the game, and myself included, but I heard the noise from the boys and ran over to join the celebrations."
The Warriors claimed a dramatic six-run victory against the New South Wales Blues when Peter Nevill was caught reverse sweeping Ashton Turner with just ten balls remaining.

The Redbacks coach was captain of the last South Australian side to win the Sheffield Shield in the 1995-96 season, and admits that his young group will need to learn from last year's final in order to claim victory against the Victorian Bushrangers on Sunday.
"We've been talking more about last year's final and giving ourselves another opportunity and hopefully learning some lessons from that game to bring into this one.
"We don't have anything to lose and it's not necessarily their home ground and the Duke's ball will give us a good chance to bowl them out.
"They beat us last year and it would be nice to turn the tables," he said.
