I think oceanography sounds great, especially if you have an interest in fish and live near the ocean.. but i agree with gormo, introduced species sounds much easier :-)
Meh, oh well... It will still be funner than working at maccas and earning 5c an hour (no offence to all the ppl working at maccas hahaha). I'm doing the aptitude test tomorrow... should be fun. Hopefully they won't tell me that all i'm good for is a janitor or dish-pig :-)
Yeah I suppose that sounds alright... It's not like you pay tax on the money you make, so i guess with the subsidised cost of acommodation, it evens it out a bit.
