alternative teaching practise voluteering australia.

Hi my name is ZOE and Im in my 3rd year at Uni, studing Primary Education.  We are encooraged in this year to arrange an alternative practise placement  to enrich my studies and gain Knowledge in a different area and country.   I am trying to raise funds to sponser this travel. I can get no help through college.  I only have my student grant to fund this venture and I am at present looking for a job but this is difficult to fit in around my teaching placement, studies and planning for my teaching practise which takes up most of my time.  My parent help most they can but are unable to support with money they are struggling to make ends meet themselves.  They can not  fund my trip without getting into dept.  I am hoping to volenteer at a Koala sanctuary in Australia for 2 weeks then 2 weeks in a local school,  the cost of this is 500pounds  then flights and living exprences.  I worked out would cost approx 2000 to cover all costs.  I feel if I dont try and somehow fund this  this year  I will never be in a position to do this again. Next year I will be a qualified teacher and will need to get a full time job.  Any support would be gratefully received and I feel the Knowledge I will gain and the experience would be invaluable to my future development as a Primary School Teacher.  THANK YOU.
