Australia's Test bowling stocks lack any fear factor, according to South Africa batting coach Neil McKenzie.

But while McKenzie believes Australia lack an express quick, the hosts still boast potential match-winners in the three-match Commonwealth Bank Test series starting in Perth on November 3.

"I don't think it's the fear factor, it's more most of the guys are worried about losing their wicket, not about the fear factor," McKenzie told reporters in Adelaide on Wednesday.

"That is how it probably should be.

"But the bowlers are still quality, can still get you out and can still win Test matches for their country, so they have still got to respect whatever comes out there.

"You don't have to look too far past most of the guys' stats, I know they have five or six seamers up for selection, they're all quality seamers.

"I don't know if the 150kmh is still there ... (but) it's a quality bowling line-up. And behind the stumps there is still enough aggression."

Spearhead Mitchell Starc is the Australian paceman likely to nudge 150kmh with support acts Josh Hazlewood and either Peter Siddle or Jackson Bird providing more accuracy than pace.

But McKenzie said there was no chance of South Africa underestimating Australia despite a recent 5-nil whitewash in a limited overs series.

"I don't think you can be under-rated ever, especially in Australia," he said.

"We know there's a rich history, lots of tradition and a lot of pride in performance."

McKenzie said the tour game would act as a switch for the tourists, who played a pink-ball day-night match against a Cricket Australia XI last weekend.

"Now it's just back to red ball, getting the techniques organised, getting the minds right," he said.

"Everyone is in a good mental state, everyone has had a good run at this stage.

"The coaches are happy with where we are. 10 days before the Test match"
