This is not entirely correct. The insurance is activated by spending $950 on any aspect of the trip - not just flights. So you can book your hotel/s for example, and if the cost is > $950 it doesn't matter how you pay for your ticket, FF points or not.
From the PDS:
Cardholders, their spouses and dependent children become eligible for this International Travel Insurance when, before leaving Australia on an overseas journey, they have a return overseas travel ticket, and at least:
(a) A$950 of each of the cardholder’s, spouse’s and dependent child(ren)’s prepaid travel costs (i.e. costs of the return overseas travel ticket; and/or airport/departure taxes; and/or prepaid overseas accommodation/travel; and/or other prepaid overseas itinerary items); or
(b) 90% of each of the cardholder’s, spouse’s and dependent child(ren)’s return overseas travel ticket(s);
is paid for by one or a combination of the following payment methods:
• charged to the cardholder’s eligible credit card account; or
• paid for by the redemption of the cardholder’s Commonwealth Awards points through the Commonwealth Awards Program, this excludes points redeemed for Frequent Flyer programs;
and, in the case of the spouse and/or dependent child, they are travelling with the cardholder for the entire journey.
I have just rang up Zurich to confirm that I am covered for my travels
