HI guys i received this voucher in email. I am not an NRMA member but was in the past. I still keep getting their offers though. The voucher seems to have no minimum to spend and doesn't really specify it's for members but one can try their luck. Last time i enquired about one their deals as a non member and they mentioned they can book me the deal but will charge me additional $90. I think this voucher can cover that well. They have some nice travel offers on their website.
Or you can join their club care member offer which includes all travel discounts. The joining fee is a one off $55 plus $24.40/year. I think once you become a member then this voucher can cover that cost. I am sure the voucher can not be used to pay for the membership. A little investment.
Mod: Added international travel to title
Valid only for international travel. It's on the voucher, but worth putting in the title.
