Chris Lynn admits he has a point to prove in Australia's Twenty20 international against South Africa after a hot and cold one-day series.

But the master blaster reckons he won't change his freewheeling approach in Saturday night's one-off T20 on the Gold Coast.

Lynn, 28, has turned heads with his pyrotechnics in T20 leagues around the world but has shown only glimpses of his firepower for Australia.

He pummelled the Proteas with a whirlwind 44 in the second ODI in Adelaide but amassed just 59 runs at 19.66 in the 2-1 ODI series loss.

It was a missed opportunity for Lynn, who's keeping his fingers crossed he still makes the flight to the 2019 World Cup in the UK.

But the frustrated Queenslander hoped to finally cut loose in his pet T20 format on Saturday night and silence the critics.

"I still want to prove a point. I feel I still have a lot to offer international cricket and while the dominoes haven't lined up yet I don't think it is too far off," Lynn said.

"Personally I feel I am in a good space and hitting the ball well.

"It's why international cricket is the best in the world. If you don't rock up with your A game you get sorted out and South Africa have been on top of their A game."

Lynn may be misfiring on paper but the Australian X-factor wasn't tempted to rethink his technique, vowing to adopt the same attacking mindset at Metricon Stadium.

"I don't think I will change at all, to be honest," Lynn said.

"The runs haven't been there but just because you miss out a couple of times you don't change the whole game plan.

"We want to go out there and throw the first punch and put them on the back foot.

"In Twenty20 some nights it will come off, others it won't. That's just the way it goes - hopefully the luck of the bounce goes my way."

The one-off clash with South Africa will be the first T20 international held at Metricon Stadium, ushering in a three-match T20 series against India before the summer Tests.

Lynn said it was important Australia bounced back in the T20s or it may be a long summer against India.

Australia start their four-Test series against India in Adelaide on December 6.

"It is huge if we can start winning momentum in the Twenty20 series because I think the Test series is going to be quite challenging against India," Lynn said.
