Savings Tips

Can anyone give me some tips on how to save some money?

My partner and I earn about $1100-$1200 altogether in a week, we pay

$430 on rent a week,

$130 on bills a week,

groceries (about $250 a fortnight).

debt at $130 a week which will last for about 1.5years,

a fine which is $110 a fortnight,

and we have a cruise next year at $850 that we need to start paying asap.

Savings would be emergency money and spending money. I just need some tips from people on a budget please...
