Not too sure of address's but one by the name of "ZETT"boxing equipment at bankstown or "SHOGUN"boxing and martial art equipment in penrith.You'd probably be able to google them to find out particulars.But if its just gloves,skipping rope's and the usual stuff you could probably just try your local "REBEL","PAUL"S WAREHOUSE"or the like,hope that help's.
if your after gloves and shorts and all that one just opened up at the entrance its called fighters domain. good little shop and relatively cheap too. of course rebel sport carries all the boxing gear you need but youll have to pay through the nose for it.
If your able to get into Sydney Zoey's Boxing and Martial Arts Supplies on the Princess Highway in Tempe has everything u could need... tey will have a much better range of gpretty much everything that Rebel sport could offer
titleboxing.com is a great site but be carefull how much you purchase as import taxes can apply and the postage can get costly, ive purchased quite a bit of gear from them and never had an issue. Shogun martial arts is also good, purchased a few of the interlocking gym mats and a box protector from them, they are very good to deal with. Brian from RedCornerPromotions also used to sell some Madison gear and a few other items, im not sure if he is still selling but he is also great to deal with, purchased quite a few gloves him him yrs ago for PCYC. It took a while for PCYC to pay him and he was quite understanding and easy to deal with. Good Luck.
I just got a mate to get me a pair of Cleto Reines 16 oz. gloves, here best price $325, through him in Mexico, $8o Aus.
