I had been living beyond my means for some time and knew I needed to trim my spending. For the last couple of years, I had been pretty careful with purchases, but was not succeeding in 'cutting my coat according to my cloth'. About eight or nine months ago, I decided I would only spend cold hard cash. I withdrew what I could afford to once a week from the bank and forced myself to make do with that until the following week. What a shock! The first couple of weeks, I was penniless within 24 hours and had long lists of unpurchased 'necessities'. My grocery shopping barely covered the bottom of the trolley. (What a joy when it came to unpacking it!) I discovered I could do without many things and started making all food (including bread) from scratch. Most things tasted better and I enjoyed cooking. I started buying vegetable seedlings and growing them, but have had to trim that back to seeds to supply us with enough. The junk food and alcohol are long gone - the money never makes it that far. I lost weight! But I still wasn't making ends meet, so I had to cut back on contents insurance. The result has been that I am more careful with what I do have and am becoming less concerned about material possessions as I am not acquiring expensive new ones anyway. I had more free time on the weekends as I didn't 'have' to scour the newspaper for the best buys and then rush around putting them on the credit card. However I still needed to trim my expenses, so I had to forgo my medical insurance. I find I am now so much more careful with my lifestyle, diet and exercise and I suspect it is because my subconscious knows that there is no comfortable private hospital or top specialist waiting for me if anything goes wrong.

Petrol is still a thorn in my side and I am very conscious of the percentage of my hard-earned money that is going on harming the environment just to get me to work. Tomorrow I have an interview for a less 'glamorous', but otherwise similar job within walking distance of my home. This would also increase my exercise. So far, the follow-on effects of spending only cash I have in my hand have not ended. But each time I have had to make a tough decision about which 'necessity' to forgo to live within my means, I have discovered that going without is not as bad as I feared and that, oddly enough, I am now healthier, happier, less rushed, more in control of my life and proud of my resourcefulness than I ever was when I had everything I thought I needed.

After reading The $21 Challenge, I thought I would see which other areas of my life I could apply the Challenge to.

First, I opened a separate bank account and now deposit $21 every week before I do anything else with my money. I see this as a type of retirement fund – it will be nice to see the funds in 30 years time!

My next $21 Challenge is to only put $21 worth of petrol in my car each week. I will park my car further away from where I need to go; this will save money and improve my fitness and wellbeing.

When my phone contract ends soon, I am going to challenge myself to spend no more than $21 on pre-paid phone credit each month - now that will be a challenge!

There are so many ways we can implement the $21 Challenge in our lives, thanks to Fiona and Jackie's inspirational book.

When I separated from my husband and was left with three children, I had no income apart from the pension. Food was getting very scarce, so I had to become creative. Every second week I drove to Flemington fruit and vegetable markets in Sydney (about closing time when most food is the cheapest), bought food by the boxes, and spent the whole day processing it. I made vegetable lasagnes, which I would freeze, all sorts of sauces, vegetable selections for stir frying and steaming, mango ice blocks (pureed mango only) and so on. We would use the most perishable fruit and vegetables the first week and the others later. Eventually we started to have an overabundance of food.

Then I told a few friends of my system, and very soon I was running a little co-op. I started to go to the markets every week and buy a greater variety of food. I got my fruit and vegies free and could also split up my petrol bill for the week amongst participants of the co-op. They got their food much cheaper than in the shop, and I got my food and petrol free.

Apart from that we had the freshest food, with fresh fruit or vegetable juices every day. Out the window went fizzy drinks and any convenience foods. It is now about 14 years since we started to eat like this, and we don't even have a family doctor, because we hardly ever get sick. How much we saved on medicines I cannot even begin to calculate.

I am putting an end to my bad habits for good! I decided to give up one bad habit a month this year - something that costs me money and is not good for me. At the end of each month, I can reward myself have that thing again but I find after not having it for a month I no longer crave them any more!

For January I gave up chocolate. It was hard at first and each time I wanted a chocolate I had to deny my cravings. I also made sure that I did something positive, such as going for a walk until the craving passed. I also made sure that I didn't buy something more expensive to replace what I was giving up. The idea is to save money and look after my health.

When February came I allowed myself chocolate again but found I didn't want it any more! For this month I have given up fruit juice. I am finding that I actually enjoy drinking water and if I need more flavour I just squeeze some fresh juice into it.

In March I plan to stop catching the bus. Instead I am going to walk the 40 minute trip to and from work each day. Although it will take an extra 20 minutes of my time each trip, I will get 40 minutes of exercise for a cost of 20 minutes. Again I hope to continue this indefinitely.

In April I will give up alcohol. When I am out I will order a soft drink or lemon, lime and bitters, which will save me money and be good for me.

Each month I plan to give up something that is small but costly and not so good for my health. By the end of the year I should end up with a lot more money in my pocket and be far healthier too!

I was usually a pretty prudent shopper but was always looking at the money I saved as potential cash for more purchases. This meant that in the long run I didn't really save anything and ended up with a heap of things I didn't really need.

I started taking a 'savings purse' with me to the supermarket when I did my grocery shopping. Instead of buying the product I would normally have bought, I would choose the cheaper alternative. For example, I would purchase the 'home brand' biscuits for $1.00 less. That $1.00 would go into my head as a saving. At the end of that shopping trip I would put any 'savings' into the savings purse. I was stunned. After two weeks of shopping and 'saving' this way, my savings purse contained $100.

I began to use my savings purse in other ways. If I managed to refuel my car with cheaper fuel, I would put the difference in the purse. If I wanted a chocolate bar, and I resisted buying it, I would put that money in my savings purse. Even with those small amounts, the savings became huge. Doing this began to be fun; it was a challenge to find extra ways to put money into my savings purse!

To top it all off, not only was I saving money but, by 'resisting' the sweets and chips so that I could put the money into my purse, I was also eating healthier and losing weight. I am so happy with the results.

I found a way to save almost $50 a year on liquid hand soap with hardly any effort! Just take a bucket filled with four litres of water. Drop a bar of generic soap into it and let it soak for 24 hours. Give it a mix and pour into clean two-litre milk bottles. Just top up pump bottles when needed. For a little added luxury, add half a cup of sorbolene cream and a few drops of glycerine. Works a treat!

This Christmas, I have saved myself over $1000 on buying gifts AND was able to afford a holiday for two to Queensland, just by using my green thumbs!

Instead of spending $50 on each Christmas present this year, I decided to use up some of my left over garden pots. I wrote a list of all who would receive presents this year and allocated a pot for each person (I also set aside five extra pots for those last minute gifts).

I thought about each person and what might compliment them, then I set to work! My garden is full of herbs, so I took cuttings from each herb and began growing them in their new pot for their new owner. I gave them plenty of time to settle in by Christmas.

When it comes time to give these lovely potted herbs as gifts, I also attach a recipe, so the recipient knows how they can incorporate their new plant into their cooking, or make up a lovely hand cream or bath bomb.

If you have herbs of your own and pots sitting around it's a great way to put them to good use. These lovely gifts didn't cost me a cent! I already had the herbs in my garden, the pots in my shed and instead of buying extra potting mix, I used soil from the garden that the plant was already used to growing in!

I make this vegetable pasta sauce for three reasons - it's cheap and healthy and it uses up leftover vegies (cooked and uncooked) so I save three times!

Whenever I serve up a dish of vegies for dinner (usually broccoli, carrots, beans and zucchini in my house) and it isn't all eaten, I put the leftovers in a ziplock bag and throw it in the freezer. Then, when my fresh vegies are starting to get to that 'oh dear' stage, I start cooking!

In a big pot, with a bit of olive oil, I fry onion and garlic and add all the 'oh dear' vegies - sometimes there is a fiddly bit of broccoli that is too small to use in a meal or carrots that are starting to wilt. Other vegies I have added include celery, cauliflower, broad beans, spinach, cabbage and capsicum. I chop and cook all of this - in summer I add fresh tomatoes, in winter I throw in a couple of cans of Home Brand tinned tomatoes. To this I add the frozen leftover vegies, a squeezie stock concentrate or stock cube and some water.

I cook the whole lot until everything is soft, and then I blitz it in a food processor or with a Bamix until it looks like pasta sauce. I then freeze this in meal-size portions and use it for everything - I add it to mince for bolognese, or just use it neat. My kids don't know it's full of vegies - they just think it's another jar of commercial pasta sauce!

This super basic mince recipe saves me up to $100 a month on takeaways, thanks to the convenience of having meals already 'half made'.

All you need are:
2kg minced beef
2 cups of red lentils
2 tbsp of vegetable stock powder, or four vegetable stock cubes
1 tsp dried garlic granules
1 dsp dried onion flakes
4 cups of water.

Place all the ingredients into a crockpot and cook on high for two hours, stirring every 30 minutes. It should be thick, aromatic and an unattractive brown colour (don't let this worry you!).

One batch costs just $13 to make and is enough to serve as a base for seven meals for our family (two children and two adults). This saves heaps of money and time too. I usually freeze the mince in margarine tubs, as that seems to be the right amount for one meal for our family.

The meals I made are:

1. Piemaker pies.
   Allow one heaped tablespoon of basic mince per pie. Pour the mince into a small saucepan and add a large spoonful of gravy powder, or a dessertspoon of cornflour and some Vegemite for colour. Heat and stir until thickened. Spoon into pastry cases and cook in the piemaker.

2. Mexican enchiladas.
   I use Mountain Bread or make my own crepes. Lay the bread or crepes in u-shapes in a large baking dish. Mix the mince with an equal amount of tinned or home-made refried beans. Spread the mixture in a sausage shape down the middle of each crepe, fold each side of the crepe over, sprinkle with grated cheese and bake at 180C until the cheese is melted and bubbly. Serve on a bed of rice, topped with natural yoghurt and some salsa.

3. Stuffed capsicums.
   Halve enough capsicums for half or one per person. Spoon the mince straight into the capsicums, top with some mashed potato, pumpkin or sweet potato. Sprinkle with cheese and bake for 40 mins at 180C. Kids love these as the capsicum sweetens when baked.

4. Baked spuds with topping.
   Allow one potato of appropriate size per person. Cook in the microwave according to manufacturer's instructions. Split a cross in the top and pile filling into the opening. Top with natural yoghurt or sour cream and chopped, sauteed bacon. Allow one large tablespoon of filling per potato. Mix the filling with one tin of baked beans and heat in a small saucepan before pouring on to the potatoes.

5. Spring rolls.
   Mix about four tablespoons of mince mixture with a packet of cooked and cooled Two Minute Noodles, some shredded carrot, and 1/2 teaspoon Chinese five spice. Using filo pastry sheets or spring roll wrappers, fold a small handful of filling into each spring roll. Spray liberally with cooking spray and bake at 180C for 20-30 mins.

6. Greek pasta bake (Pastito).
   Heat a container of mince mixture with a 400g tin of peeled tomatoes. Cook enough macaroni for your family and drain well. Mix with the meat mixture and spoon into a large baking dish and top with your favourite white sauce or cheese sauce. Sprinkle on some grated cheese and bake for 40 minutes at 200C.

7. Shepherds pie.
   Add any vegetables of your choice to the mince mixture. Place into a baking dish and top with mashed potato, pumpkin or sweet potato then bake until heated and the potato browns.

With a combined effort, we have been able to purchase the majority of required household items for several families in our community, without incurring any extra debt. By using a common practice from our country of Papua New Guinea, we have been able to join together as families to help each other with basic needs.

Along with other women from Papua New Guinea, we have moved to Paraburdoo, a mining town in Western Australia, due to our husbands'
jobs. In the first month, all families contribute to buy one family's basic need; like a washing machine, freezer, dryer, lawn mower and so on. The next month we contribute and pay for another family and cycle goes on until all families own one item each. Whilst waiting for our turn to come around, the first family that has the item allows us to share it until we have our own and so forth.

The next big project will be assisting each family to obtain a second hand vehicle for starters, then when we have settled in and are mobile enough, we can trade-in the second hand vehicles for brand new ones to suit the timing of each family.

By putting in the effort as a group, we are able to achieve our dreams within a reasonable time and without going into debt. Our culture embodies this practise of sharing and helping each other, and it has worked just as well in Australia as it did for us in Papua New Guinea. A positive outcome which may invoke similar thoughts among close friends and neighbours in other communities.
