However, it was not the Thai golfer's superb seven-under-par 65 that Els found himself mostly talking about afterwards, but one particular shot from Belgian Nicolas Colsaerts.
The Open champion could not believe his eyes when Europe's biggest hitter launched a drive of 419 yards at the downwind third hole.
"I've been coming here since 1986 I think and I've never seen a ball there, nobody has," Els said.
"They should put a plaque down. I was coming from a different zip code. And I've got to compete against these animals!"
Els had the last laugh, though. He matched his playing partner's birdie and out-scored him by five to keep his victory hopes firmly alive.
Jaidee, part of the 33-strong winners-only field thanks to his victory at the Wales Open last June, was out on his own from the time he birdied six of the first 10 holes.
The 43-year-old led by five at one point, but that was cut to three late in the day despite the two South African stars having to contend with heavy rain.
"We probably got the bad side of the draw, but that's part of golf," said Oosthuizen, who faced similar conditions during his runaway seven-shot win in the 2010 Open at St Andrews.
He and Els still had the advantage of local knowledge, however. Jaidee is on his first-ever trip to South Africa.
"I enjoy the course," he said. "You have to think a lot - I hit the driver on only two holes - and put a three-iron in my bag only 15 minutes before we teed off."
Seven players share fourth place in the race for a first prize of almost £283,000.
There was a 10-minute hold-up on the opening green because the flagstick was stuck in the hole and damage was caused in yanking it out.
"I've never seen that before," said Lawrie, who then came close to winning a £32,000 excavator when his six-iron tee shot to the 170-yard 15th hit the flag, but stayed out.
Jamieson knows only too well what the weather can be like in the city. It was only last month that he won at nearby Royal Durban in an event reduced to 36 holes because of rain.
Padraig Harrington began his 2013 with a 70, but Paul Casey - winner in Bahrain two years ago, but unable to defend last year after dislocating his shoulder snowboarding - could do no better than 74 like Jose Maria Olazabal and Darren Clarke was one worse than that like defending champion Branden Grace.
Clarke's fellow Northern Irishman Michael Hoey would have shared second spot with three closing pars, but instead double-bogeyed the 16th and 18th for a 72.
Hoey reckoned he had drunk too much water. "I felt bloated and lost so much concentration," he said.
The former British amateur champion will need his focus back for the second round. Amateurs from the final of the Volvo World Challenge join the action for one day only.
