Ok.
We have internet and mobile phones with separate companies. When we moved last time, we could only get wireless broadband internet from Telstra (the only thing anyone else could offer was dial-up ... there was no adsl on our side of the street )

So - this is my budget for a fortnight
Internet - $75
Mobile - $91 - this is for mobiles
Electricity - $50
Food - $ 170

I have other expenses - like cc, student loan and daycare, but I'll keep those a secret

My internet bill will change next month, as we are now living in an area with adsl. So it's gone from $139.95 a month to $80 a month (we had to get a home line installed, but we're not telling anyone the number and it's only there for adsl. We have a big cap on our mobiles, so we use them for everything !) Next time we move, we need to find places and contact the internet provider to see if it's an adsl area.
