you'll be stuck interstate anyway -(where's the oP from?). if you take bonded you'll be sent to RRMA2 places for another 6 years when you around 30~40. if you are a rural/suburban person it's probably no big deal, but a lot of city folks tends to be a bit picky in that regard.

It depends, I live just over an hour away from the city and it's RRMA 2, despite this the area that I live in is sitll considered to be part of the Greater Sydney. Many other city centres such as Wollongong, Geelong, etc are also currently RRMA 2 aswell.
RRMA 2 is by no means 'rural', at all. Also you won't "be sent", you get to choose where to work within RRMA 2-7 regions (as long as there is a shortage in the area, which most of them do have) and you have the flexibility to practice anywhere within these regions. However, by the time you graduate and are in a position to work this may have all changed. You should also consider factors such as family, extended family and friends, etc.
Department of Health and Ageing - BMP Scheme - Where can I work?
Personally I'd take the UQ offer, it's a year extra but I think you will be able to personally gain alot from undertaking a undergrad degree before med. Plus you get two degrees.
If I still was inclined to do law with medicine, I would definately take the Monash offer, even though it was bonded.
