we live in brissy and our little man hasnt arrived yet but i think australia zoo (at beerwah its about an hour and 1/2 drive from springfield) little one will get much more out of it that the other theme parks. if you have any problems you could always buy the stroller when you get here as you said you were going to buy a cheap one here is a shopping centre in springfield. you would have to hire your car from the airport or somewhere that would deliver it to the airport unless you plan to train then bus it to springfield, its a $90 plus taxi fare from the airport otherwise. have fun.
