Currently the exit to the Sportsplex Parkway is registered as a road to the left shortly before the roundabout. 

However, Sportsplex Parkway is meanwhile an exit of the roundabout itself, making it the first exit. 
Travelling South, i.e. driving through the roundabout and staying on Warnbro Sound Avenue requires to take the second exit.
