Perth Scorchers opener Herschelle Gibbs is confident he can continue his Twenty20 career into his early 40s, but concedes his chances of breaking back into South Africa's national side are now officially over.

Gibbs, who turns 39 in February, remains one of the most destructive batters in T20 ranks.

But the powerful right-hander hasn't featured for South Africa since 2010 when he was axed from both the one-day and T20 sides.

After cracking 302 runs at an average of 43.14 for the Scorchers last summer, Gibbs held out hope of breaking back into the national line-up in time for the recently-held T20 World Cup in South Africa.

But after being overlooked for selection by coach Gary Kirsten, Gibbs concedes he won't get the chance to shine on the international stage ever again.

"Gary said that the door was still open last year in the Champions League. There's no door at this stage, that's for sure," said Gibbs, who notched 90 Tests, 248 ODIs and 23 T20s for South Africa in a decorated career.

"Maybe I should knock and then it might open.

"Ultimately I'd still like to be playing international cricket.

"But I've had to move on and accept that I won't play that again, and make the most of it.

"There's certainly enough competitions around the world to become a T20 specialist. You have to do well in order to be invited back again.

"It's very much a pressure-driven environment. I'm sure there will be quite a few players that will become T20 specialists (over the coming years) for sure."

Gibbs will be aiming to repeat his Big Bash heroics when he lines up for the Scorchers in the October 9-28 Champions League T20 tournament in South Africa.

Perth kick off their campaign against the Titans on October 13, before taking on Kolkata Knight Riders, the Delhi Daredevils and another team yet to be determined.
