Sorry Lost, I never use the digital yellow pages, it either sends you off on a whole different world, or know not what it speaks
eg: Squeeez Fruit Bar at Mudgee sells a 10ltr container of ice for $3, but yellow pages won't point you there
must admit 100% the same, but thats what came up when I googled... so it *COULD* be right.
I just searched for Dry Ice Dandenong and got
Sound FX DJ Service
Sound FX DJs Will Not Only Meet Your Expectations,We Will Exceed Them!
One way to do it is to find a BOC depot or Air Liquide (I used to deliver pallecons of dry ice to them), they sometimes can help you out.
I'd have thought somewhere where boats come in could help out, like Port Fairy maybe?
