As I've said before, I am not paid by or affiliated with any companies or organisations. I'm providing these links here because these are websites I personally find useful, not because I have been asked to post them. I will add more as time goes by, or if somebody emails me with a review of a website they have enjoyed.

I have bought a lot from HSD over the years! You can find all the big-name brands on their website, as well as many smaller 'boutique' brands and generic products at a lower sale price. Shipping is very decent in terms of price and has always arrived very quickly and in perfect condition. The prices you get on HSD is a lot lower than the in-store retail price, so I recommend them for shopping online!

Another great online saddlery is Kingston's as although they have a slightly smaller range of products than HSD they have some really nice, quality saddles and many pieces of tack that you wouldn't otherwise be able to find. They have lots of Australian brands which is nice if you want to support Aussie jobs!

The Rug Rack specialise in show sets, so they make rugs, hoods, boots and browbands to measure in your choice of fabric and colours. They have some really cute rugs available, all at a very nice price, and some lovely browbands to choose from. Would definitely recommend their diamante browbands!
HORSE HABIT- http://www.horsehabit.com.au/index.asp
Horse Habit specialise in co-ordinated tack for individuals as well as Pony Clubs and riding teams. They make just about any piece of fabric tack from saddleblankets to boots, exercise sheets, girth covers and more in your choice of colour and style, and often also in your choice of fabric. They also make helmet covers which are great for PC events and gymkhanas, as well as tail wraps and saddle covers- cute!
Newmarket Saddlery- http://www.newmarketsaddlery.com.au/
Newmarket is very popular in NSW and across Australia for good reason- they provide quality products at low prices, and ship them direct to your door. The great thing about Newmarket is that if you have many horses you can buy in bulk for an even greater discount. Newmarket's website is not an online store, as they operate via catalogue orders. You can view or download their catalogue on the website, or email them to have it posted to you. I have purchased items from Newmarket quite a lot and I have always been really happy with the service and the products.
http://horserugcleaners.com.au/
The name says it all! Horse Rug Cleaners operate within Australia only and you will need to check their website for the drop-off points where you can have your rug collected and cleaned. However, if there is a location near you then you are a lucky person! You can have your rugs and saddleblankets washed professionally, waterproofed and repaired for a low price, and have them come back looking new. What more could we want?
http://www.gohorse.com.au/
While I haven't personally purchased anything from Go Horse, I have looked at their website and seen a lot of rugs and other items that look nice and for a very decent price. If any readers have bought from this website please let me know so I can write a better review for them!
SUPER CHEAP SADDLERY- http://supercheapsaddlery.com.au/
Similarly to Go Horse, I have not yet purchased anything from Super Cheap Saddlery, however I have been eyeing off some of those rugs! There are many features on their rugs that are similar to the 'big name brands' but at a much lower price. If anyone's tried this website please let me know!
http://horse-connection.com.au/index.html
Horse Connection is well known in Australia for being the major supplier of treeless and flexible-tree saddles. If you're thinking about trying a treeless saddle then I would recommend contacting Horse Connection, they have many distributing points and they offer a trial period for saddles so you can figure out if it's right for your horse or not.

Equestrienne = <3 Seriously, I am in love with this website. It's so easy to navigate, really nice to look at and best of all they are selling quality 'big name' products at a fair price. I am so tempted to buy even more horsey stuff to fill up the shed!
