Wrong, it would be a DONE5 per the rules from
Other Conditions section on page 1 of the Oneworld Explorer rules, shown below:
Travel between South West Pacific and Europe/Middle East on a single flight number/or by surface eg LON-SYD/MEL/PER vv, DOH-ADL/AKL/CBR/MEL/PER/SYD vv, is considered travelling via Asia. Continents South West Pacific, Asia and Europe/Middle East must each be counted.
