PS We always look at Scoopon and Groupon deals as well and have used many for parties !

We did once a night walk through the forest and the boys all had to bring their flashlight. Ending by a restaurant with a low prices menu, where they had dinner. After dinner they walked back and had a sleepover.
We also have done the cinema and a meal at the foodcourt.
An other time we did bowling with a simple meal.

Movie night with pizza and popcorn or camping sleepover night

It depends on the childs interests.
Sports are usually a good idea. You could go to a local park with some sporting equipment.
There’s also the cinema, depending on how many children would be attending the party of course.

The first place to start when organising a birthday party is by looking at what the child enjoys doing, what would his friends enjoy. It’s really hard to make suggestions without knowing this

Pool parties are cheap.

If there’s a local bush/oark area around you, then you can organise you’re own kind of paintball competition. Divide the boys into 2 teams and give each of them a bucket with 10 water balloons each and the task of capturing the other team’s flag. If you get hit with 3 water balloons, you’re out of the game and you have to go and eat the food for a while while the game plays out. Very cheap and the boys will love it.

bowling movies are great fun….

there are some good comments here

a disco would be heaps of fun

Sports store voucher or sporting equipment is always a winner here!
iTunes cards are also popular

Some local parks have pathways all around where the kids can ride their scooters, and there are bbq facilities there you could make use of too.

How did the party go?

Every kid has different ideas of fun, ask him if he would like to go bowling or would he prefer something more out doors.

At 13, our son loved movies, pizza and having a few good mates over for a sleepover,

What did you end up deciding on?

Try going to a skatepark or bike track.. take some party food and a cake
Themed party at home like trash pack or whatever he is into
go to a local pool its pretty low cost

You could always just go somewhere like timezone, laser tag, bowling etc and put on invite we are going to such and such for sons b’day if you would like to join us word nicely everyone pays for themselves ?

Movies and junk food, and a sleepover in the lounge room is always going to bea good party!

A race in the park?

i hope it turned out great
