Thanks - will look into your suggested routing, but any transit in Jakarta is not high on my list of things to do. I only need 1200 SC to renew Platinum, so anything over this will be a bit of a waste. Getting maximum FF points is a higher objective. I am also going to go to Brisbane a couple of times this year, so I will get my 4 Qantas flights. But this year is the exception. Last year I only did 2 Qantas flights in total (return economy to Brisbane), but my Platinum was renewed as I got over 2100 SCs the previous year.
Here is the flying I have done to date, so you can see the gaps I am trying to fill.

So you can see why I was thinking about going via JNB and Finland.
Does the 10 day rule also apply to tickets started in South West Pacific, as it doesn't for the Star Alliance RTW tickets.
