I’ve been reading about some of these lectures on the blogs of students who attend the college.
Lectures are available for free download and rss subscription has now been added so that new material will be automatically downloaded to your preferred syndicated content manager.
These links will take you to the relevant area on the Queensland Theological College lectures and sermons page:

I’ve got the first 4 sets of the Culture vs. Cross Culture addresses which Bruce Winter gave as public lectures at Creek Road PC. They’re great stuff and well worth circulating to others.
