A whois lookup on one of your domains shows that it is registered through godaddy.com and points to your jelly.com.au current host. It's registered in your name, but maybe the people at jelly.com.au did the actual registration. So you probably don't have a login at godaddy.com. The domains might not even be locked.
If you go to godaddy.com, there is a support contact form and phone number. They probably have something to go through to prove who you are. email@example.com is listed at the administrative email address. You could email them and find out what you need to be able to login and unlock your domains, if they are indeed locked. Both parties should help you with this. I had a client who let her ISP register her domains and had no idea how to get them transfered. I called the ISP and they were basically clueless. Then I called the registrar (Network Solutions!) and they said, "have the client call us and verify a couple of things. It will be no problem." It ended up being easy for her and she knew nothing about the process at all.
