hi am after grolsch bottles in west perth area but prepared to travel to get some

This might be a tough task for you.
These seem to be favourites with every homebrewer who gets hold of them.

You could always try e-bay.

ps. I'm a clogwog (dutchman), and Grolsch is my favourite Dutch beer. When I was last in Holland 10 years ago, I used to buy these at the local supermarket for the equivalent of AUD $1.
