I'd end up using the front rows for 40 each so it doesn't make too much difference, but it's possible they'll want to limit BPA's minutes with Porecki injured again on the weekend. Tthe main reason I started Asiata though, is that Asiata, Salakaia-Loto and Uru make up the bones of an established lineout that is already coached by the coaches in charge of this side.
The other aspect is that he and Samu are the only Aussies in this squad who haven't faced the Lions yet, which means they should definitely be in the 23 for mine and probably starting. I'd also pick them on merit though, so that's just an added bonus.
