Evan, I have an app on my Desire HD where I stream radio (the ABC being one of them). Will you have mob reception where you are? The app I have is "TuneIn".
If you're going to the beach on the far north coast of NSW I can tell you the frequency for ABC.
dont know if the info is timely enough but 97.3FM will give you the cricket out of ABC wollongong, im picking it up clear in the Sydney CBD, will depend on where you are located i guess
