What was the name of that koala cartoon?

This was a cartoon movie in the late 1980s or early 1990s. It must have aired on the Family Channel in Canada, but I think it was Australian originally, or at least set in Australia. The main character was a human girl, and I think she had a sick koala, and she had to earn money to get him medicine? At one point, she's performing and sings a song that goes "And here's a tip/go take a trip..." and then she's interrupted by someone who gives her bad news and she says "Oh no!" and runs off.

Does anyone else remember this cartoon movie?

What Was The Name of that TV Episode?

I think this was an episode of a TV mystery show. I want to say Matlock, I'm pretty sure it wasn't Murder She Wrote, but it could have been Perry Mason (90s edition), or Diagnosis Murder, or something like that. There were twins, adult female twins, but a fingerprint examination revealed that the twins were actually just one person pretending to be two. I think they used Scotch tape to lift the fingerprints? And there was something to do with an elevator. This was probably sometime during the 90s.

Does anyone remember this but me?
