It has long been possible to redeem American AAdvantage miles for travel on Fiji Airways. However, there has just been an update to the types of redemptions that are possible, as flagged by @TheForwardCabin.
American AAdvantage updates Fiji Airways award pricing
American AAdvantage seems to have rolled out dynamic award pricing on Fiji Airways. Or more specifically, you can redeem AAdvantage miles for a seat on just about any Fiji Airways flight, though the pricing reflects demand for a particular flight.
For context, one-way saver awards between the United States and South Pacific have historically cost 40,000 miles in economy or 80,000 miles in business class.

However, now you’ll find that some one-way awards between these markets cost as much as 67,000 miles in economy, or as much as 267,000 miles in business class.

Pricing is arguably even steeper on the short flight between Fiji and Australia, where business class costs as much as 135,000 miles one-way.

Why American has added dynamic awards on Fiji Airways
While American has long had dynamic award pricing for its own flights, the program hasn’t historically had dynamic award pricing for travel on partner airlines. So, why has the program introduced this on a partner? Well, it’s likely not a coincidence.
Fiji Airways is shortly joining the oneworld alliance, and on top of that, is even going to use American AAdvantage as its own program. Just as American offers dynamic award pricing for its own flights, it’ll do the same for Fiji Airways.
Presumably the two airlines have some financial arrangement whereby it makes sense for Fiji Airways to make more award seats available at a higher cost. I also suspect this means that Fiji Airways will shortly be fully integrated into AAdvantage.
As things currently stand, I wouldn’t at all consider this to be a negative development. There’s a limited amount of saver award space, just as before, but there’s now also the opportunity to redeem in situations where there’s not saver award space.

Bottom line
American AAdvantage has rolled out dynamic award pricing on Fiji Airways, making this one of the first times American has offered dynamic pricing on a partner airline. Presumably this reflects that Fiji Airways is going to use AAdvantage as its loyalty program, so just as American has dynamic award pricing, the same will apply on Fiji Airways.
