Jerry Attrick,
Good for you - go for it!
I don't think you are too old. My friend's exflatmate started at QF LH 5 years ago...she's now 44. Another friend's exwife started at QF LH when she was 28 and after 1 1/2 - 2 years was promoted to first class cabin crew. I think it comes down to attitude and being able to do your job well. Impulse are recruiting at the moment and if you go to the Australian Airlines website you will see that they will be recruiting very soon.
Good luck with your career!
Cheers
