Award travel won't get you RDM/EQM miles, so I don't usually use award tickets for myself and just use them for family traveling with me. If you think about it, if you pay for the Australia ticket, you will be getting 17K miles + 100% bonus which is 34,000 RDM miles. That's close to halfway to another saver award ticket to Australia and since you travel for business frequently, you won't have to worry about expiring miles and can use those miles for the next family trip.

But then, you would have to reach 1P before your trip to get the 100% bonus. You can also hope for another DEQM, do a cheap MR, and may not need the Australia trip to make 1P.

*G is nice, but in my opinion, by far the best benefit of 1P>2P is the 100% RDM bonus, so I take advantage of it as much as possible.
