New South Wales Disability Parking Sticker - Use overseas
While in London last August, I found out that there is a reciprocal agreement between NSW and the UK regarding the use of my blue NSW disability parking sticker
I used it to get disability parking when attending a function at Epson Downs racecourse. I also received a discount at Poy du Fou (a French theme park) when I hired a mobility scooter.
There were more options available but I had no need to use them
I had a picture of the parking sticker on my phone which was acceptable in both instances.
Look up the specific requirements in the countries that you intend visiting, as we all know that there is nothing logical when it comes to beaurocracies.
