Replying to Is it possible to get a second working visa?

I've been dating an Aussie since last March, and now it's looking like we are running out of options. I met her in Park City last March when she was over here on a one year working visa which ended in December. She came back on a travelers visa for about a month, and I just recently visited her in Australia. But now we are at a point were we can't afford to keep making trips. I'm still finishing up school so moving to Aussie isn't really an option. I know there is marriage, but that's sorta last resort. I'm just curious if there is any other way for her to get another working visa. I'm sure a few people on her have dealt with dating someone from another country. Any insight would be great.
