Just to be clear, the Garmin GPS does not provide maps, they come to you from the Internet, so if you are in the field away from WiFi and your tablet does not have a cellular connection, you cannot access 'new' maps. All the Garmin provides is the GPS co-ordinates. But it will provide a much more accurate GPS location than any GPS built into a phone or tablet, so that is one thing it is good at.
It is essential to have an Internet connection when using the search function, because as soon as you perform a search, the maps application makes an enquiry via the internet to locate the area you asked for. But you do not have a connection to the Internet because your tablet does not have cellular capability. The maps you are seeing have been cached while you had a WiFi connection.
No, you do not have to buy an 'Australian' map, you just use the normal Apple or Google maps.
