Hi willyroo, thank you for the Australia web link provided. Do you know if they allow reservation to be made without advance payment? I'm thinking of reserve to collect in Perth city then pick up when I arrive? Thank you.
No reservation, Officeworks is a large office supply retailer similar to Staples or Office Depot in the states.
But if you already have a gps try googling "free gps maps australia" -- there are at least 2 freebies that seem to have pretty good reviews.
