All the action from the Pool C match in Brisbane.
80 mins: Replacement Neil de Kock ends the game as he links up out wide for his try. Koen's conversion ends the game.
Samoa 10-60 South Africa
78 mins: Dominic Feaunati almost restores some Samoan pride as he rips apart the Springbok defence but his pass goes forward.
75 mins: Van der Westhuyzen takes his side's points past the half-century mark as they dance their way past a tired Samoan line-up to add insult to injury. Louis Koen converts.
Samoa 10-53 South Africa
73 mins: Willemse shows immense pace for the second time as he fires down the right flank. He pops it to Jacque Fourie just two metres out and he scores his side's sixth try.
Samoa 10-46 South Africa
71 mins: Samoa will be looking to make one final mark on the World Cup before taking their tournament bow. Lima has a go, the South Africa tacklers have other ideas.
68 mins: Willemse finally has the chance to show his pace in this match. A lot has been said about his speed and he sprints from within his own half as Samoa fail with their own attack.
Samoa 10-41 South Africa
66 mins: Richard Bands and Leupolu come face to face for a word or two, after some nasty stamping by Krige. The referee intercedes and Samoa win a penalty.
64 mins: South Africa's drop-goal practice is showing no signs of improving as Muller messes up yet another. That's not a ploy they will want to try against New Zealand.
63 mins: Hougaard is left reeling on the ground after an absolutely massive tackle from Lima. It's a tad high, but the referee decides quite rightly it's legitimate.
62 mins: Hougaard clinches his first penalty of the night.
Samoa 10-34 South Africa
60 mins: So'oailo is losing patience as he keeps on failing to set the game alight. His frustration hands South Africa a penalty as the Samoa's throw a last roll of the dice with a host of replacements.
57 mins: Samoa win penalty after penalty past the Springbok 22 but fail to make it pay. In the meantime, van der Westhuizen is receiving treatment. But he looks to be alright.
55 mins: Brian Lima is the latest Pacific Islander on the burst, smashing through his first two tacklers before being felled around the neck. The referee lets it go and Lima concedes a penalty for holding onto the ball.
52 mins: South Africa come within a whisker of a try with an attempted interception but it just manages to go to Samoa's Maurie Fa'asavalu instead. He charges through the Boks defence but he and the ensuing attackers cannot quite find the line.
49 mins: Muller this time steps in for Hougaard for a drop goal. The gathered spectators are suitably dismissive of another poor effort.
47 mins: Samoa are doing absolutely everything to run South Africa ragged and to good effect. After dominating possession and territory, lock Opeta Palepoi bulldozes his way and just manages to score in the right-hand corner. Va'a slots over a massive conversion.
Samoa 10-31 South Africa
45 mins: Van der Westhuizen fires up a delightful box kick for his attackers. De Wet Barry gathers it and goes for the glory rather than give it to Willemse and is left to dwell on his greed as the try goes begging. Meanwhile, Samoa charge 70 metres up-field.
43 mins: Vili leaps for the finest catch of the game. He is immediately brought crashing back down to the ground.
41 mins: Danie Rossouw comes on for Joe van Niekerk, while Tamato Leupolu replaces Jeremy Tomuli.
40 mins: Hooker John Smit is the surprise producer of a stunning dummy, which sends Juan Smith through to touch down. It really is game over as the whistle goes for half-time.
Samoa 3-31 South Africa
39 mins: South Africa try and pick up another try before the interval but the usually reliable van Niekerk is the latest Bok to knock the ball forward.
37 mins: Drop goal attempt number three from Hougaard, and howler number two is the result. Even his team-mates have to chuckle.
36 mins: Hougaard links beautifully with his fellow runners to send his team-mates on their way. Thinus Delport takes it out wide but he and Jaco van der Westhuyzen, the player he passes it to, totally mess it up and the ball goes forward.
34 mins: You wonder how Samoa are ever going to get back from here. Their pack is really struggling to keep up with their opposite numbers.
31 mins: Smith is very lucky to avoid a sin-binning as he is penalised once again for coming in on the side.
30 mins: Juan Smith is penalised for going offside in a kickable position for Samoa. Much to the crowd's delight, Va'a kicks for touch and an attacking line-out. They mess it up, though, and Hougaard clears.
27 mins: Hougaard makes amends for his terrible drop goal as he hacks the ball ahead and beats Semo Sititi to ground the ball. He converts his own score.
Samoa 3-24 South Africa
25 mins: The biggest cheer of the night goes to Hougaard for a dire drop goal attempt. There was never any hope of that going over.
23 mins: South Africa get back on the attack in an instant but van Niekerk is dumped by Brian Lima and a scrum is called.
20 mins: The Pacific Islanders unleash their first real attack of the game, oddly enough launched by hooker Jonathan Meredith kicking ahead. Lome Fa'atua sprints down the right flank but is pushed into touch. It at least gives their rivals something to think about.
17 mins: Samoa desperately need to regroup under this fiery onslaught. They look a shadow of the side that ran England so close.
15 mins: Hougaard juggles a disastrous pass with delight before sending a tricky grubber kick forward. Vili is there to gather and boots it away with four attackers within grappling distance of him.
12 mins: Samoa are struggling to keep up with South Africa's expertise in the scrum. Once again the Springboks use it to spread the ball wide. Jorrie Muller is the man that finds his way through this time, dragging Romi Ropati over the line with him.
Samoa 3-17 South Africa
9 mins: Hougaard restores his side's lead to seven points with a drop goal. It brings a flurry of boos from the crowd.
Samoa 3-10 South Africa
7 mins: Hougaard intelligently chips forward, Steven So'oailo knocks forward and the Boks once more line up for an attacking scrum. It ends in disarray as the final ball to Ashwin Willemse flies into touch.
4 mins: Samoa win themselves a penalty following some indiscipline in the South African pack. Earl Va'a takes the three points.
Samoa 3-7 South Africa
2 mins: Joost van der Westhuizen breaks from the base of the South African scrum, sending through the superb Joe van Niekerk, who shuns his tackler to score. A blistering start for the 1995 world champions. Derick Hougaard seals the conversion.
Samoa 0-7 South Africa
1 min: Springbok captain Corne Krige sets the trend for his side by taking the catch at the kick-off and charging 15 metres up field.
0737 GMT: Tanner Vili hoofs the ball towards South Africa to get this do-or-die Pool C game under way.
