I am not really sure what exactly you are looking for but here are some suugestions:

You have excellent physiotherapy education institutions in Queensland = particularly Queensland Uni - still you may no more about that than me. Have you thought of doing something at a post grad level that may cover the territory?

If you want just to do short courses. Are you a member of the APA? You could see what is on offer on the professional development schedule - see what the Musculoskeletal SIG is offering. Even if you are not a member as I really you can usually do their courses - they just charge you a bit more.

Personally I found Shirley Sahrmann's approach both sound and practical. It would be good if it was supported by a bit more evidence but it has good plausibility and I found it practical for patients. It aims to address the underlying problems give rise to much of what we see in MSK physiotherapy that isn't due to an acute injury.

I don't know if someone who represents her offers courses in Australia. She used to visit Australia and NZ regularly. You can contact her faculty at the University of Illinois
Courses on Diagnosis and Treatment of Movement System Impairment Syndromes

Have you read her book?

Amazon.com: Diagnosis and Treatment of Movement Impairment Syndromes (9780801672057): Shirley Sahrmann PT PhD FAPTA: Books

You can also get her book through Physiobobs. Her approach isn't particularly symptom relief oriented so if you want to go for that then I am sure there are heaps of courses you could do. The Myofascial Trigger point approach is one common approach and has some evidence for it. Personally I found it works quite well in conjunction with more general chronic pain management techniques and with Sahrmann's approach
