Morne Steyn grew up idolising Jonny Wilkinson and now he's aiming to break Australian hearts in similarly deadly fashion in Saturday's Tri Nations Test at Newlands.

The Springbok five-eighth has been in imperious goalkicking form this season, topping the Super 14 pointscorers' chart to help the Bulls to the title before further wowing fans with his spectacular entrance to Test rugby.

On his Test debut last month, Steyn drilled a 55-metre penalty after the siren at Loftus Versfeld to clinch South Africa's series win over the British and Irish Lions, and last week he sensationally scored all 31 of the Springboks' points in their triumph over the All Blacks in Durban.

Now the 25-year-old says he'd love nothing more than to follow up his Tri Nations record haul by putting the boot into the Wallabies - like Wilkinson, who famously sunk Australia with an extra-time drop-goal in the 2003 World Cup final in Sydney.

"Yeah, that's a thing that any player dreams of," Steyn said when asked if would like to replicate Wilkinson's heroics on Saturday.

And it's not like Steyn hasn't given himself the best chance of doing so.

"My hero as a teenager was Jonny Wilkinson. I watched him closely and read his books and the message from him was simple - practise, practise, practise, and I kick on average 300 balls a week," the humble fly-half said.

Steyn admitted he sometimes has to pinch himself so meteoric has his rise been this season.

"It's like a fairytale for me. I have to keep my feet on the ground and stay calm," he said before vowing not to yield to the pressure of maintaining his 90 per cent goalkicking strike rate in his first five Tests.

Ironically, Steyn was regarded more for his running game than his kicking earlier in his career.

And he proved he was no one-trick pony last Saturday when he scored South Africa's only try against New Zealand with his under-rated speed.

"The gap just opened for me so I'm just lucky. I don't score that many tries but now and again, when I get one, it's great.

"(Bulls coach) Heyneke Meyer told me I must work on my tactical kicking to play at a high level and that's what I did and I think my kicking and running is now up to standard, both of them."

Steyn will get another opportunity to show his class when he faces Wallabies superstar Matt Giteau at Newlands.

"It's nice for me to pit myself against the best in the world to see where I am," he said.

"So I am looking forward to this one."
