As we wrap up our postings about Brisbane, sharing a few "lessons learned" here hopefully will prove helpful, or, at least informative:
There is a lot to experience in Brisbane, but know that this city is not quite as walkable as was Melbourne. With that being said, their public transportation system is excellent, and is easy to use (once you understand it). Like many cities we've visited, Brisbane's public transit runs on a ticket system. Those tickets can be purchased at any of the major downtown stations, or at the many 7/11 stores located around the city. These "Translink Go-cards" are the cheapest way to travel the city, especially for Seniors (i.e. Half-price). You do have to remember to tap the card when you get on the bus AND tap again when you get off, or you'll be charged a full fare (which is the most expensive way to go). As mentioned before, when we first arrive in any city, we tend to take a taxi from the airport to the apartment. Then, once we've become accustomed to traveling around, we use public transportation to return to the airport.
In every place that we've visited during this journey, one of the first things we do is to find the Tourist Visitors Information Center, not only for a street map of the city we happen to be in, but also to learn about when attractions are open for visits ( every country has its own holidays when places are closed). This is also the place to learn about what attractions are available for no charge (including free walking tours. You can even arrange for an individual free walking tour based upon a particular theme - such as the Aboriginal tour or the World War II tour).
Make sure to leave time to visit Mt. Coot-Tha (for great views of the city) and the Botanical Gardens. Bus #471 will take you from King George Square to the top of Mt. Coot-Tha, will wait five minutes while you enjoy the view and take some pictures, and then brings you part way down the mountain to the marvelous Botanical Gardens. This bus runs only once per hour, so you do need to keep track of your time.
