Brunswick is becoming a desirable suburb, and it's attraction is due to it's proximity to the City and cafe's, restaurants etc.
The better parts are Brunswick East - particularly around Edward Street. Brunswick West has moved ahead substantially, although there are some Housing Commission Towers here that you may want to stay away from.
Perhaps if prices come down over the next year or so, you may find a house for around $500,000. But only time will tell!
I think Brunswick will be very expensive in 10 years time, and probably hard to buy into.
