I haven't looked into O+G because it's not a career path I'd ever want, but generally speaking - it makes no difference. Theoretically, we should all be on the same playing field after med school is done. Edit: looking at the O+G points system there do seem to be points for rural background, I'd say this is unusual among colleges, and I struggle to understand the motive behind this. A cursory look at various RACS scoring schemes confirms this. Furthermore, looking at the Vic internship system, rurality certainly does not play a role.
