The 18-year-old, who made a sensational Test debut by taking seven wickets to set up a thrilling series-levelling win for Australia against South Africa earlier this month, is looking forward to bowl against Tendulkar in the Test series next month.
The 38-year-old Tendulkar made his Test debut three-and-a-half years before Cummins was even born.
"He's one of the greats of all time, I've grown up watching him," Cummins told 'The Sydney Morning Herald'.
"For someone who is a bit of a pocket rocket, he's not too tall, even against the fastest bowlers he seems to stand up and lift another gear.
"To get a game, even here in Australia, would be unbelievable. To be versing the likes of Sachin Tendulkar, Rahul Dravid - it's going to be a massive challenge. He's someone hopefully all the bowlers don't get too overawed versing him and I guess you've got to still imagine him like any other batsmen," he added.
India and Australia will square off in a much-anticipated Test series starting December 26. Cummins said he would not "waste time" chalking out a bowling strategy for Tendulkar as the Indian is "too good everywhere".
"It's more imagining the moment of playing people like him, it'd be a massive thrill," Cummins said.
"Sachin Tendulkar has got a massive following in India and is a rockstar over there. Someone like him, all the fame, it'd be on a whole new different level versing him," he added.
