Id recommend the Perth Barista Academy in Northbridge (mod edit commercial link removed)
I did a half-day introductory course there (for $150 - work paid :) and I was impressed. Awesome coffee and top-flight equipment. The course was very enjoyable, but also very informative and practical. It was a mix of home enthusiasts, people applying for serious cafe roles and kids just leaving school and looking for some cred to apply for basic cafe roles. I seem to recall that I walked away with about 10 coffee shots in me and a cash voucher to buy some beans.
You may want to give them a call to chat about actually doing the course though, because all their equipment is stand-up operated - and I dont know how that would work with a busted ankle?
Hope that helps
