I'll break down your questions into parts
:
Is that an overdone piece from the list?
Because its such a short list, no piece is really more overdone than any other. Make sure you rehearse as much as possible. Don't just do it in your head. Physically stage it (but no set or props obviously), and pay attention to your delivery. Make sure that you can pronounce each word properly.
Do most people sing with the accompaniment? Or acapella?
Varies from person to person. Pick whatever your comfortable with. I choose Acapella, because I could do it how I wanted without fear of the piano causing problems. If you don't have the proper version of the piano music, then I'd suggest Acappela, as you can rehearse it more often, as you don't need someone to play the piano part. Also, you can adjust the tempo to whatever you want.
Are there any over done songs?
Funny story. I changed my song the day of the audition, once I was there. Turns out the girl who went in before me did the same song.
As for overdone songs, I suggest you read:
MusicalTheatreAudition.com - Overdone Audition Songs
This is a list of commonly overdone songs. However, if you can do one of them well, then don't let that stop you from using it.
Do people normally do pop or musicals?
A lot do musicals, as you can put a degree of character into it. However, it is in no way an obligation.
Do they allow you to sing all the way through or stop you half way
What I suggest is that you only do a short segment of your song (say, 1 verse, bridge, and chorus). That way, you'll leave an impression with your song, without needing to be cut off for going too long. Have a second song, or more of the first prepared just in case. However, it is highly unlikely you'll need it.
Is it in front of other applicants or in a seperate room?
You go into a seperate room. It's the main performance theatre.
Panel will consist roughly of:
1. Head of Department
2. Sub Head
3. Singing Coach
4. Movement Teacher
5. Character Teacher
6. Production Teacher
7. One to three students from my year.
There may be a couple of others, like Honours students, or additional lecturer. Try and make eye contact with the people asking you questions, and make sure to try and focus your attention on each of them at some point. You will probably only get questions from one or two of them.
Do they interview you after either the song or performance - what kinda stuff do they ask?
As above, they will ask you questions. You'll do the song, then the performance. Then questions. Things like:
Why do you want to do this course?
What are your theatre interests?
Who inspires you?
Where do you see yourself in the future?
Most inspirational theatre experience?
What experience have you had?
Approximate ATAR?
Are there any other parts of the process? Like an assessed warm up and activity beforehand?
You will do a movement exercise. Don't try and parody their instructions(especially if they ask you to do a slow race [you'll see what I mean if you get it]). You'll also do a group based task. Don't go for stupid jokes, play strong characters. This will all happen aften your solo audition. Most likely after lunch.
That said, bring lunch and water. A book or an iPod could be useful as well. Also, get talking to people. It's likely some of them will make it into the course, and its good to know someone on the first day.
