I would recommend HIGHLY training at Basair, its a long established school, the guy who runs it Darrin taught me my instructor rating back in 1990, he was a great instructor 16 years ago, and I dare say he is still a great instructor running a great school. His knowledge and experience back then, has helped me a lot in my career that has now spanned 5 countries.
Go for the Oz training, it will be much better quality (instructor licensing and training levels are a bit higher in Oz than the USA) than the Florida training, plus you will see busy airspace, mountains, and desert all within 2 hrs flight in a PA28 of Sydney, that ain't going to happen in Florida!
