Hi zarf4 and row2aisle, thank you so much for your insightful advices. For a first time gps user and traveler to Perth, the pois will definitely be very useful, thanks for highlighting this point!

Row2aisle, may I know why you purchase the garmin maps from amazon and not the local garmin distributor? Is it cheaper?

Zarf4, thanks for Recommending officeworks. In the event I do not get a good deal locally, I'll definitely be going there to get my gps. Thanks again.
