Qantas Gift Vouchers with child booking

[LadyC]

Hi Brains Trust
I have done a quick search and couldn't find an answer to this question. Earlier in the year I bought a gift voucher for myself, the Gentleman and MasterC. When you buy a gift voucher, you can't (or if you can I didn't see it) choose for children, you just get number of pax and it is assumed they are all adults.
Now I am considering redeeming the gift voucher for an international flight, although I assume the same theory should apply for domestic flights too. I can only redeem MasterC as an adult. Would this cause an issue if we turned up at check in and rather than 3 adults, there was 2 adults and 1 child? Do I need to call Qantas to get the gift voucher adjusted to recognise that MasterC is a child? Any tips from those who have been through this process before?

I’ve booked Miss H on GVs previously without issue. But they’ve all been straightforward Dom. bookings where there was no fare difference for a child.

I have once booked international by phone and the operator applied the voucher.
