Of course but this wont be handed to you. You need to have years of experience and/or a Master's degree to be qualified as such.
It is faster/easier to get a senior role in aged care compared to theatre BUT the pay is lower.
Why are you so worried about the pay rate? You are just a newgrad right?
In general there are people who could live off with $25/hr working just 30hrs per week while there are those who get bankrupt despite earning millions.
I dont know what you consider a great pay rate but here in australia, year1 RN working fulltime gets paid $28-30/hr (80hours per fortnight) depending on the facility. Your hourly rate is higher being a partime or casual staff but your hours would be less. Keep in mind that we RNs are on an hourly wage so the more hours we work, the more money we make. Our hourly rate increases anually until we reach YR8.
You want to earn more, then do agency or volunteer to be oncall, work on weekends/holidays, take OT, etc but most importanly, have the experience first.
