Hi
with your budget a house or area will not be a problem. Since your husband will be working on St kilda road, tram would be the quickest way to get to work so what I will do is give you the tram routes that way you have an idea of what suburbs the trams run through.
MELBOURNE Train & Tram map if you find Albert park, St kilda road runs next to it.
I have also a junior soccer web site listing all the clubs for your kids
Football Federation Victoria as for your other son if you go to
google.com.au and type in
junior drama clubs melbourne loads of sites will come up.
If you can work out what club your 2 boys want to join and the drama club that your other son likes on the tram line that goes past your husband works, You have found the suburb thats right for your family (cross fingers)
Other than that travel on a few trams and you should get the feel for what you like.
I hope this info has helped
Enjoy your trip let us know how you get on, if you need any more info just let me know
Geoffrey
