The Party Hive is an excellent place to go hire a helium tank and balloons if you feel comfortable inflating your own. The helium tanks are quite easy to use although make sure you park close to the door as they are very heavy when full. The also have various other decorations and party supplies.

i find the party hive at gungahlin to be a great place, i get all of my party things from here. they give great advice, give all their time in helping, have a great range of things for any Occasion. they have a kids corner so the kids can play while you shop. i find the price is fantastic. you get what you pay for, good money for great advice, great service, and fantastic quality of products. i will not shop anywhere eles, and if they dont have something they will get it for you. id love to know where eles you could go to get this kind of service its rare to find. The party hive RULES

Pretty expensive but a good range of bits and pieces. Balloons excellent - great range of different ones and pretty prompt in providing them, even while you wait.
