Hi Lynda and welcome aboard.
Being in a remote location does throw up some unique extra weight loss challenges, but I'm sure you can overcome these with a few ideas and a little support from all your new friends on the weightloss forum.
Successful weight loss for some is easier getting help from the likes of Jenny Craig, WeightWatchers, Ultra Lite and the like, but it is possible without such help in cases such as yours.
For example, you'll find plenty of useful information in the diets section of this website regarding diet and we are adding new features all the time (such as nutritional tables which we are in the process of adding now).
You'll find the diets section at: http://www.weightloss.com.au/diets.html
With regards to not having access to a gym, you can create a gym at home like I've done. Your home gym needn't be complicated or expensive to set up, all you really need is a Swiss Ball and a set of dumbells and you're in business. If you don't already have a Swiss Ball, you can even order one from the weight loss shop on this site.

One thing that you've got going for you that many of us don't is wide open spaces and plenty of fresh air and sunshine to go walking, jogging, hiking and bicycling in.
Sometimes instead of concentrating on what we don't have, it is better to focus on what we do and simply use them to the best of our ability.
While exercising with others can be more fun and motivating, if you don't have anyone to exercise with because of your remoteness, simply join in on the exercise forum discussions and you can "share" your daily exercise with others (simply knowing someone else is going to be exercising today - even if it is in another location - can be very motivating, as can posting a note on the forum afterwards and receiving the encouragement from your cyberfriends for doing so.
Why not ask the forum members if there is anyone else who has similar remoteness issues and ask how they are or have overcome them - we are all here to help you in whatever way we can.
Good luck with your weight loss Lynda, I know you can do it despite your additional obstacles.
I look forward to reading all about how you've overcome them and succeeded - in fact, I look forward to you teaching us all how to overcome such obstacles.
Speak to you again soon.
