Advice needed on travel from Perth to Dubai mid to late next year

Hi guys.

I am planning to travel from Perth to Dubai around (June-Sep 2018). I have got qantas ff points. I want to ask what are my best options to travel business / first class return.
I have seen that Cathay Pacific is available in those dates. I guess i can use qantas points on Cathay Pacific being a partner of 1W airlines.

Any suggestions will be much appreciated (I want to minimize the taxes/ surcharges, fly business/ first class, that’s what i have learnt thru this site in last 8-9 months :)…

Thanks to Keith and the all the other wonderful guys.

Cheers.
Hassan.

by searching different flight options you can see taxes to be paid.

note that going via hong kong is a lot longer than direct flight

 

ps please avoid abbreviations such as 1w. no one uses that
