If you sign up for Smart Traveller, they provide a few coupons which include one that gives you access for a single child 11 years and under to Plaza Premium lounge for free.
The QR is issued as part of your Smart Traveller sign up and is valid for 90 days.
'Each voucher entitles the voucher holder to enjoy a complimentary lounge access for the accompanying child with age 11 years old or below at any one of the Service Locations on or beore the indicated expiry date…Member must present the voucher via the mobile app and Smart Traveller ID at reception to redeem the reward'.
So if you have a Priority Pass or Dragon Pass that gets you and a guest in, this saves you an extra $35 USD fee on my Priority pass for a kid as many lounges still charge for kids.
Going to Gold Coast for a week end of Feb with wife and a kid, will this benefits us in any way if sign up?
