I was looking for Sydney Airport parking for my Easter break. I googled it and found the promo code SPACE10 and it is valid for the Easter break.
I booked for 10 days and cost me $126.90
Please note: Booking fee of $1 is redued to 90c after the discount
I hope it could help some people who started looking for Sydney Airport Parking. Enjoy!!
Its cancellation policy is also better than Park on King. Wilson Parking allows full refund if you cancel it at least 1 hour before the entry time. (Just in case if the border is closed again)
