Are my calculations correct? Sniip bill payment at 1.5% credit card surcharge

I’m looking to pay an invoice for a family member via Sniip.

Invoice is $15904
Credit card surcharge is 1.5%
= $238 approx

I’d also get additional 1 Qantas point per $10 spent so the $15904 would mean another 1590 Qantas points.

So all up, 17494 points for $238.

23800 cents / 17494 points = 1.3c per point

Buying 17,000 points direct from Qantas would cost me $570.

It’s worth going the Sniip route?
