paging sunscreen experts

DH is heading to Australia on a business trip soon and IIRC I remember
hearing several of you saying that the most effective sunscreens are only
available on that side of the world......could someone be so good as to name
a few products and maybe stores where they could be purchased? Thank you for
any help!!!

I think you can get Anessa there which is a Japanese brand often raved about
here. I don't know where you could purchase it.
