RMIT.
I say this because I am a schoolteacher and know many friends that have gone through the BEd at RMIT. No complaints. I can't really comment about Swinburne but I haven't heard anything nor know anyone that goes there.
Important thing to note is that a BEd is nearly the same anywhere you go - the main focus for you is placements and how they operate them. Some require you to go and get your own placement (which can be really daunting especially if you've never had to do something like that before) and some that do it all for you.
Will you use the content in your BEd? Eh, probably parts. I know from my perspective I haven't used anything from my MTeach. It's such a dynamic discipline.
The goal for you throughout any degree whereever you go, is to build networks, perform well during placements and actually finish the degree. You'll know within days of your first placement whether you are meant to be there or not.
