The second Test between South Africa and Australia gets underway in Gqeberha on Sunday, with Australia carrying a 214-run first-Test win into the match and South Africa making significant changes to a batting line-up that was second best throughout. Among those changes is the inclusion of Marques Ackerman as a likely debut Test opener — a decision that shapes the opening partnership market in a very specific way, and one that the 17/10 available about Australia registering the highest opening partnership is built squarely around.
South Africa are fielding a debut opener in Ackerman while Australia’s Head and Maddinson represent an established Test pairing. With SA batting fragile overall — bowled out for 284 and 206 in Durban — and Hazlewood and Cummins among the world’s best new-ball operators, the tourists hold the structural advantage at 17/10.
Why Australia Stand Out in This Market
The Betting Case
The highest opening partnership market is a head-to-head between two teams’ first-wicket stands. It does not require either side to bat brilliantly — it only requires one side’s openers to last longer than the other’s before that first wicket falls. And that framing is where the case for Australia becomes considerably clearer than it might first appear.
South Africa have made sweeping changes to their top order ahead of this match. Tristan Stubbs and Kyle Verreynne have both been dropped, with Ryan Rickelton taking the gloves despite having never kept wicket in a Test match. To allow Rickelton recovery time after his keeping duties, Marques Ackerman is set to be pushed up to open the innings — potentially on debut. That is not a settled, confident opening partnership. That is a makeshift arrangement driven by necessity, and it is the single most important structural fact in this market.
Consider what Ackerman is walking into. Australia’s bowling attack in the first Test was formidable even without full firepower: Josh Hazlewood took 6/49 in the second innings; Pat Cummins claimed 3/52 in the first. Mitchell Starc is in the squad. These are not bowlers that give inexperienced openers the benefit of the doubt in helpful conditions.
And the conditions here are worth examining separately. Gqeberha’s pitch at St George’s Park is historically spin-friendly later in the match, but the first innings tends to produce more traditionally paced conditions before the surface breaks down. The weather forecast adds another dimension: overcast skies and rain are predicted for days one and two. When a pitch is under covers for extended periods and the atmosphere is heavy, seamers find movement. That can cut both ways — Australia’s openers Travis Head and Nic Maddinson will not find it easy either. But Head and Maddinson are established Test batters with international experience at the top of the order. They are not walking into a debut Test alongside a team-mate who has only just been asked to open because the batting order needed reorganising.
Maddinson’s 48 off 38 balls in the second innings of the first Test illustrated what he can produce when he gets in — a quick, aggressive contribution that has him in good touch going into this fixture. Head is a consistent presence at the top of Australia’s order. Their first-wicket partnership may not be a long one, but the comparison here is relative to whatever Ackerman and his partner manage against the Australian seamers on what could be a challenging first morning.
South Africa’s batting in Durban was broadly poor. They were bowled out for 284 and 206 across two innings, with only Aiden Markram (37 and 75) and David Bedingham (49 and 46) offering sustained resistance. Neither Markram nor Bedingham are openers — they bat three and four respectively. Whatever Ackerman faces at the top of the order on Sunday morning, he does so without any established evidence that this South African top order can weather Australia’s attack early in an innings. The first Test confirmed precisely the opposite.
At 17/10 (decimal 2.70), this is a short-odds proposition rather than a longshot — the market considers it roughly a coin-flip with a slight lean towards the SA side or the two outcomes being close. The argument here is that it is not close: Australia’s opening pair is structurally more stable than what South Africa are putting out, and the first-Test batting context strongly supports that view.
Key Betting Snapshot
Market Value Assessment
What Does 17/10 Ask the Bettor to Accept?
At 17/10, the implied probability is approximately 37%. That reflects a market that sees this as a competitive proposition — not heavily tilted in Australia’s favour, but not a pick ’em either. The question is whether 37% is a fair representation of Australia’s actual probability of producing the higher opening stand, given everything set out above.
The case for the price being on the generous side rests on the structural mismatch. South Africa are fielding a makeshift opening combination under pressure, against an attack that has taken wickets freely throughout this tour. Australia’s opening pair, by contrast, are both experienced at Test level, with Maddinson in obvious form and Head a reliable presence at the top of the order. The contest between a settled, confident pair and a reorganised, debut-level combination should not be a 37% versus 63% split — the structural gap is wider than that.
There is a counter-argument around the venue: South Africa have won their last two Tests against Australia at Gqeberha, and Kagiso Rabada — now returning to the South African XI — took 5/96 and 6/54 at this ground when they beat Australia by six wickets in 2018. Rabada is an elite new-ball bowler and he will target Head and Maddinson from ball one. If he replicates anything close to that 2018 form, Australia’s opening stand could be brief. That is the genuine risk in this selection, and it is the reason the confidence rating sits at two rather than three.
The 17/10 is not a reflection of Australia being a heavy favourite in this specific market. It is a reflection of genuine uncertainty. The argument is simply that the structural case — one settled pair versus one debut-level arrangement — is tilted enough in Australia’s favour to make the price worthwhile.
The key distinction in this market is not about which team wins the Test or even which team bats better overall. It is about the first wicket of each innings — specifically, which team’s first-wicket partnership runs deeper. South Africa’s reorganised top order makes that a question with a reasonably clear answer when the two sides’ situations are placed side by side.

How the Highest Opening Partnership Market Works
Beginner-Friendly Explanation
The Highest Opening Partnership market asks a simple question: which team’s opening batters — the two who walk out first — will put on more runs before the first wicket falls? Each team bats twice in a Test match, so this market may apply to a specific innings (typically the first innings of each side) or across all innings — check the specific bookmaker’s settlement rules before placing. You are not betting on the match result, who scores a century, or how many wickets fall. You are backing Australia’s two opening batters to have a longer partnership than South Africa’s two opening batters before the first dismissal.
Australia’s established opening pair face a South Africa top order that has been reorganised under pressure. Ackerman’s potential debut as opener against a high-quality Australian attack is the central structural advantage. At 17/10 the market offers a price that reflects genuine uncertainty while the structural case favours Australia.
Kagiso Rabada’s return is a significant threat to Australia’s openers. He took 5/96 and 6/54 at this venue in 2018. If he finds his best form quickly and the overcast conditions assist the seam, Head and Maddinson could be dismissed cheaply. The venue also has a strong record for the hosts against Australia in recent years.
Performance and Match-Fit Analysis
Australia’s opening combination going into Gqeberha is Travis Head and Nic Maddinson. In the first Test in Durban, the Australian top order was under pressure early — they collapsed to 124/6 in the first innings — but Maddinson’s cameo of 48 off 38 balls in the second innings showed the kind of aggressive stroke-play he is capable of when settled. Head is a known quantity as an opener at the highest level.
South Africa’s situation is considerably less stable. The decision to bring in Ackerman and push him to the top of the order is driven not by form or suitability, but by the logistical challenge of asking Rickelton to keep wicket and then bat without adequate preparation time. That is an important distinction. Ackerman may well be a capable player — he is in the squad on merit — but opening a Test match is among the most demanding batting roles in cricket, and doing so against the attack of Hazlewood, Cummins and Starc, without the protection of settled partners and a known position, creates a vulnerability that the market has not fully absorbed.
Matthew Breetzke is the likely partner should Breetzke open alongside Ackerman (the batting order specifics remain fluid). His first-class record has been described as solid without spectacular — creditable county cricket experience but not the profile of a batter who handles elite pace bowling with authority in their first Test exposures.
The first-Test evidence reinforces all of this. South Africa’s recognised batters — Markram and Bedingham — were the standouts with 37 and 75, and 49 and 46 respectively. Neither is an opener. The opening position produced nothing that featured in those batting highlights, which tells its own story about how South Africa’s top order fared against the Australian attack across both innings.
The core of the selection is the structural mismatch at the top of the order: Australia have an established Test opening pair in good form; South Africa are deploying a likely debut opener under reorganised circumstances. That gap matters most in the opening exchanges of each innings, which is exactly what this market measures.
Kagiso Rabada’s return to the South Africa XI is the single biggest risk factor. His Gqeberha record against Australia is exceptional. If the overcast conditions and the venue’s traditionally helpful first-morning surface combine with Rabada at his best, Australia’s opening stand could be shorter than expected — regardless of the South Africa top-order disruption on the other side of the ledger.
What Could Go Against This Bet?
Risk Factors
- Kagiso Rabada’s return: Rabada missed the first Test but is all but certain to play here. His Gqeberha record against Australia — 5/96 and 6/54 in the 2018 Test — makes him a genuine danger to any opening pair. If he is immediately among the wickets with the new ball in overcast conditions, Australia’s first-wicket stand could be brief despite their structural advantages.
- Venue and weather conditions: Gqeberha has produced two consecutive South Africa wins against Australia. The overcast conditions forecast for days one and two favour seam bowling generally — which helps Australia’s attack against the Proteas, but equally gives Rabada and Gerald Coetzee an enhanced platform to remove Australia’s openers early in their innings.
- South Africa’s home-match motivation: Facing a potential 2-0 series deficit, the hosts have strong motivation to lift their game significantly. Marco Jansen and Wiaan Mulder put Australia on the back foot in the first Test’s first innings (124/6) before Renshaw intervened — the South African attack has shown it can be effective, even if the backs were not to the wall at that point as they are now.

South Africa vs Australia 2nd Test Betting Q&A
What does the Highest Opening Partnership market mean?
This market asks which team’s opening pair — the two batters who walk out first — will put on more runs together before the first wicket falls. You are betting on Australia’s first-wicket stand being larger than South Africa’s. Check settlement rules with your bookmaker, as some settle on first innings only while others cover both innings.
Why are Australia being backed in this market rather than the match result?
Australia are already 1-0 up and are strong favourites for the series result. This market offers a different angle — specifically the top-order comparison — where South Africa’s selection changes create a structural vulnerability that is not fully captured in broader match-result pricing. The 17/10 offers a specific, evidence-based reason to back Australia in a targeted market rather than backing them to win the Test at shorter odds.
Who is Marques Ackerman and why does his selection matter?
Ackerman is a South African batsman who is expected to open the batting in this Test, potentially on debut. He has been moved to the top of the order to allow Ryan Rickelton time to recover after keeping wicket — not because he is the preferred opener by profile. Opening in a Test match against Australia’s attack of Hazlewood, Cummins and Starc is among the most demanding tasks in cricket, and doing so without an established role in the line-up is a genuine vulnerability in this specific market.
Who are Australia’s expected openers at Gqeberha?
Travis Head and Nic Maddinson are Australia’s expected opening pair. Maddinson scored 48 off 38 balls in the second innings of the first Test, showing he is in good touch. Head is an established presence at the top of Australia’s Test batting order and gives the pair genuine experience and stability relative to their South Africa counterparts.
Does Kagiso Rabada’s return change the picture?
Yes — it is the main risk factor. Rabada missed the first Test but is expected to return here, and his record at Gqeberha against Australia is exceptional: he took 5/96 and 6/54 in the 2018 Test when South Africa won by six wickets. If he finds his rhythm quickly with the new ball, Australia’s opening partnership could be shorter than expected, regardless of South Africa’s top-order disruption. That is why this selection carries two stars rather than three.
How did South Africa’s top order perform in the first Test?
Poorly overall. They were bowled out for 284 and 206 in Durban, with only Aiden Markram (37 and 75) and David Bedingham (49 and 46) offering meaningful resistance. Importantly, neither of those two are openers — which means there was no standout opening partnership performance to point to. The batting struggles were broad but the top-order vulnerability is a specific concern going into this market.
Does the venue help South Africa in this market?
The venue favours South Africa in certain respects — they have won their last two Tests against Australia at Gqeberha, and the pitch historically assists spin in later innings. However, the first innings at St George’s Park tends to play more traditionally before the surface deteriorates, and overcast conditions forecast for days one and two help seam bowling from both ends. The venue advantage is real for the match result but does not necessarily translate into a first-wicket partnership advantage for the hosts.
What are the settlement rules for this market — is it first innings or all innings?
Settlement rules vary by bookmaker. Some highest opening partnership markets are settled on first innings only; others consider the opening stand across all innings a team bats. You should check the specific terms with the bookmaker before placing. This distinction can affect the selection — if the market covers multiple innings, Australia have more opportunities to build a larger combined opening stand, which generally strengthens the case given the depth of their batting and South Africa’s top-order instability.
