You are not likely to receive the bonus points if you have not transferred from Platinum Charge Ascent Premium to QFF before, if the latest offer was targeted, going by the experience of a friend of mine and also what is published in a Points Hacks article. A friend who got a new Charge card last year contacted QFF when I received the offer and he didn't and was told that it was targeted and that no he wouldn't receive the bonus.
Point Hacks regularly publish articles about the QFF bonuses for transfers and they state in that article that you need to have previously done a transfer to get the offer. My friend transferred a small amount on that occasion and didn't receive any bonus points then but since then he has received the offers each time.
Here is the latest Point Hacks article about this, dated November 2, 2018:
Transfer bonuses for Qantas Points from credit cards - Point Hacks guide
Edited: Ive just looked at the email I received from QFF on 8 November "Transfer now for up to 45% more Qantas points" and it says:
"We are sending you this offer as you have transferred reward points earned on a credit or charge card to Qantas Points in the past." and "This offer is available to the recipient of this email only and should not be shared. Bonus Qantas Points will only be awarded for transfers of credit or charge card reward points to Qantas Points that take place between 12:01am (AEST) 1 November and 11:59pm (AEST) 30 November 2018." I also received the letter by snail mail a week or so earlier.
