Australia's Test bowling stocks lack any fear factor, South African batting coach Neil McKenzie says.
But McKenzie says despite the lack of an express quick, Australia still boast potential match-winners in the three-Test series starting in Perth next week.
"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 sole Australian paceman likely to nudge 150kmh with support acts Josh Hazlewood and either Peter Siddle or Jackson Bird in the mid-130kmh range.
Coupled with the lack of express pace, the first Test starting November 3 will be played at a WACA ground which is no longer renowned as a fast bowlers' paradise.
"I don't think it's the WACA of old, of 15 years ago," McKenzie said.
But McKenzie said there was no chance of South Africa underestimating Australia despite a recent 5-0 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."
The South Africans continue their preparations for the first Test with another warm-up game in Adelaide from Thursday.
The Proteas play a two-day match against a South Australian XI at beachside Glenelg Oval, their final game before the three-Test series.
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"
