Markram will line up with his teammates at Lord’s in London from June 11 to 15, in a match that could secure their names in South African sporting folklore should they win.
This Proteas group will try and do what has never been done by any of the talented players that came before them – and that is to lift a major senior ICC trophy.
The 30-year-old says this a childhood dream he never thought would ever come true.
"It's by far the biggest thing I'll ever do in my life. As a kid, I always had aspirations of playing professional cricket, but I never thought I would play for South Africa, and represent South Africa in ICC finals. It's all a bit surreal," said the excited batsman.
South Africa and Australia have a long history of rivalry in both cricket and rugby, and Markram says that definitely adds some spice ahead of the test and during the test. He also says they don’t mind embracing the underdogs tag ahead of the biggest game in world cricket.
"There's a lot going on within this test match, we obviously have a very strong history with Australia in all sports.
"Naturally, if someone writes you off, you feel extra motivated to prove them wrong, and we're on that journey, and the journey won't end until we lift the trophy," said Markram emphatically.
The left-hander and the rest of the Proteas team are aware that unlike most test series where you have a few matches to try and sway things in your favour, there’s only one chance to get it right this time around.
This is also the reason why they’ll look to fine-tune their preparations with a game against Zimbabwe in London.
"Mentally we've prepared for it, you can't afford to be behind the eight ball because there's no second or third test match to make up for it so starting well will be vital.
"The Zimbabwe game is also pivotal in our preparation, and we'll be sure to maximise every opportunity we get in the week prior to the final, to prepare adequately, whether we're out in the middle or in the nets," said Markram.
The Proteas have been quietly confident about their chances of lifting the trophy, and Markram says the key lies in remaining solely focused on the task ahead without getting ahead of themselves.
