Welcome to FT, Nikmehta!

There is no price posted for the UA/EK-RTW ex EBB. You may still start it there, but the price ex USA would apply.
You might be better off with the "18 airlines-RTW" which you call "worldperks", though domestic flights in Australia are not possible.

Prices ex EBB in business:
30K miles: 5996 EUR
35K miles: 6847 EUR
40K miles: 8062 EUR

Another possibility is oneworld with a DONE4 for 5402 EUR or DONE5 for 5865 ex EBB. This one would allow PER-BNE. You could ask in the oneworld forum for routing assistance.

Ex BKK most RTW are quite low. Ex BOM you'd have to add the new business/first class tax.
