JNB-SYD-WLG-SYD-HKG-LHR-NBO-LHR-JNB still has the problem of two African entries/exits when only one is allowed. Also it is no longer RTW (but is a *ONEWC4 instead).
JNB-SYD-WLG-HKG-NRT-JFK-LHR-NBO-LHR-JNB has the same problems wrt African entries/exits. No direct service WLG-HKG (though there is AKL-HKG). More adventurous?
