Using Qatar Platinum on QF flights

I obtained Qatar Platinum through the status match from Virgin Platinum earlier this year and have a flight coming up on Qantas. Can I get into the QF business lounge by just showing my Qatar Platinum card electronically or do I actually need to have the Qatar FF number on my booking. If the latter, can I change it to my Qantas FF number when leaving the lounge, or is that not allowed?

Also have Qatar Platinum status match and was allowed into Qantas Brisbane lounge recently using Qatar electronic card, my booking was made using my QFF which is Bronze.

You can just show the Qatar card at the entry to the lounge, even with your Qantas number linked onto the booking.

Great way to enjoy the lounge benefit, while earning Qantas Points.

Thank you both.

Ah interesting. I am in the same situation however was told by Qantas the only way I am able to have lounge access is to link it to my qantas ff.

As a Qantas Club member who also took up the Gold Status match with Qatar, does that entitle any more guests ?
