Congratulations Albert ! Thats quite an achievement especially when it is a part time course.
I know how it feels to achieve something you always had an interest in doing but on top of a full time job it is something else. I just did that myself recently at the age of 40!
Melbourne is a great city. Enjoy your stay there. As for the redbacks, I once sat at a bus stop with a whole nest of them under me. It wasn't until I saw one crawl beside me that I jumped out of my skin !!
