Have a WHV - facing a dilemma. How possible is it to start a new career on a WHV?

Hi all,

To keep things brief, I used to work in Accounting but I really did not like it at all and quit my job and travelled for a few months and now I am in Melbourne where I have a year long Working Holiday Visa.

My dilemma is:

Do I take any sort of job (like admin, call centre etc) so I can get some cash together as living on the euro out here is extremely expensive but at the same time gain no valuable experience with regards developing a career and end up in the same situation afterwards, or

Do I hold out and try find a job that could lead to something and try develop a new career from scratch. My degree is in Marketing, my passion is sport and travel, and I have recently done some writing for each. I think I would be suited to working as a travel consultant for a travel agency as I have been to so many places and know a lot about the different parts of the world. The problem is that lots of these places may not be hiring and that by looking for a job in these areas I could be waiting for quite a long time and end up going broke.

Is it really possible to develop a career on a WHV or am I destined to work in a bar/ restaurant/ call centre etc type of job?

Is this really the place to be picky?
