Penalty rates is the same as shift allowances, flat rate is about $27 per hour. Late shift is paid a further 12.5% night shift is 50% weekend work is time and a half on Saturdays and time and three quarters on sundays, then if you have another certificate ie psych then it is an extra $70 dollars a fortnight, if you are in charge of a shift it is an extra $8 per shift etc. However it is true to say that tasmanian nurses are the lowest paid in Australia as far as these rates are concerned. Again if you work for an agency on the main land then it is much higher paid hope this helps
I work in mental health in Tasmania, each state in australia has different rates so it might pay to search those rates out, we have a base pay depending on how many years post grad u are. first year out here is about 38,000 per year then you need to build in your penaly rates etc,.
