If Matt Renshaw isn't selected for the opening Test of the three-match series against Pakistan that starts on December 15, then he won't be allowed to use his day one tickets, according to his sister.

Renshaw purchased tickets to day one of the day-night Test a while ago, long before he was selected to face South Africa in the third Test in Adelaide.

Shaun Marsh is touch-and-go to be fit for the Gabba Test, and even though Renshaw has tickets to the opening day of the Brisbane Test should he be replaced in the side by Marsh, his sister won't allow him to attend.

“Yeah, I did buy tickets but it’s my sister’s graduation from uni the first day of the Test, so I’m told if I’m not playing I’ve got to go to that,” Renshaw told Triple M’s Rush Hour.

“[She] told me, my sister, that even if I’m not playing I wasn’t allowed to use the tickets.”

Renshaw's rise to fame happened quite quickly, and he almost missed out on the call up after missing an important phone call from interim chairman of selectors Trevor Hohns.

“It’s all been pretty crazy, I just thought I was going to be playing a Shield game and trying to get a win for Queensland and ended up being picked for Australia, which was an amazing feeling,” he said.

“My mum and dad got a phone call off Trevor Hohns before me, because I’d left my phone charger at the Gabba and had to keep my phone on airplane mode just so I’d wake up in the morning. So I got the phone call from dad as soon as I turned it off saying, ‘You need to ring Trevor Hohns’. So I rang him pretty quickly after that.

“It was the best experience I’ve had in my life. It was quite hectic but once I had time to think, it was so enjoyable.”

Renshaw impressed on debut in Adelaide, and scored an unbeaten 34 from 137 balls in the second innings to help guide Australia to their first Test victory of the summer.
