Using QFF Silver (or Gold) status to score free seat selection on QF branded sale fares

Has anyone ever managed to get a free seat selection on a QF branded sale flight using Emirates metal, by quoting their Qantas Silver membership?

i.e. on flights where emirates charges a fee for seat selection.

The reason I ask is that Emirates customer service always claim that "Qantas high value members can enjoy same benefits on Emirates Airlines as they do on Qantas". So if they don't allow status matches between the two frequent flyer programs (due to alliance b/w Qantas and Emirates), then logic would suggest it would be reasonable for Emirates to offer free seat selection for QFF Silver members (in the same way that Skywards Silver members can)?

Anyone have any experience with this?

Is there any chance?

Yes. Qantas silver members get free standard seat selection on EK flights.

You just need to have your Qantas number in the booking.

I usually book QF flights on Emirates metal from Perth through Dubai to Manchester. I use the Qantas website to book and also use Qantas edit bookings function for allocating seats
