Bernard, my guess is the voucher you have just recieved is not showing up on your 'Payment Methods' page as yet. If you check there under your payment method you will see current credits and coupons and an expiry date. Once a credit is used it disappears from that section.
If this is not the case Bernard, get onto Sydney on 02 85203333 and get them to sort it out.
Also, you will note that credit is $141.00 AU! It will be interesting to see if that value fluctuates with currency variations over the next year!
As far as the frequency of credits is concerned Bernard, they are issued on the aniversary of each year you have been a superhost! I achieved my first credit in October 2016 and I have now just received my third, so, I have been a superhost for three years......15/16....16/17.....17/18
Credits are not released on a quarterly basis (although assessments are quartely) they are released on an annual basis!
Good on you mate, you are going well.
And if I can just make another point, don't consider the photography.....$100 doesn't get you much of a photographer and you lose control of the photos they remain with Airbnb and Airbnb decide how they will be used!!
