"So I had to fly out straight away because they had a Diamond Challenge series on. I didn't even know the girls' names."
The two-time world championship-winning coach is now facing a vastly different coaching experience as she tries to improve her squad just weeks before the World Cup begins.
"You can't put a team together with all the polish in three weeks — not compared to four years — but what we're working on is just the major areas and trying to make sure they're skilled up in that. There's the small technical stuff which will probably be amiss because we won't have had time to work on that, but we need to get them on the court and get them balanced and being competitive."
Plummer's reign has started promisingly, with her first games in charge seeing the Proteas go unbeaten at the Diamond Challenge when they notched two wins over African rivals Malawi, their first since 2012.
Now, they have a much tougher challenge against the Silver Ferns who looked in promising form in their 91-31 win over Fiji earlier this week and Plummer believes her squad have nothing to lose as they shape up for their two-test series against the Ferns — a team South Africa haven't taken on since 2012.
"To be honest, I think the Ferns have probably got more [pressure] on them than us. We can just go in and put two and two together on some of the areas we've worked on and hopefully they can come off.
"Regardless of outcomes here, it's about the intensity and getting players very aware of what it's going to be like when they walk in the door at the World Cup, so we didn't back away from it.
"We're happy for the competition."
The Silver Ferns have revamped their squad as they look to provide a stronger challenge for Australia at the World Cup, something Plummer supports.
"I thought some changes had to happen. Whatever was there before clearly wasn't working. It's amazing what [young players] can do for you when they have quality around them. They can actually step up, so I think the Ferns can still be way up there."
