Anyone know of a place in Melbourne that sells bulk sugar(dextrose) or a website that is based in Melbourne that sells it?
Cheers,

I don't recall dextrose, but I used to do a lot of food and bulk buying in Brunswick when I lived in Melbourne, mostly along Victoria St.
I use standard table sugar for bulk priming and don't brew with sugar. Have you considered simply inverting simple cheap table sugar into the glucose+fructose constituents?
Yeast does this naturally to some extent through the enzyme Invertase. But then letting the yeast do it with cane sugar people say leads to cidery/fruity/citrusy fermentations. If you invert the sugar you will find as a brewing adjunct it is ideal as it will ferment very cleanly without having to rely on the enzyme invertase which does a not so complete inversion of simple table sugar.
Inverted sugar syrup can be easily made by adding roughly one gram of citric acid or ascorbic acid, per kilogram of sugar. Cream of tartar (one gram per kilogram) or fresh lemon juice (10 millilitres per kilogram) may also be used.
The mixture is boiled for 20 minutes, and will convert enough of the sucrose to effectively prevent crystallization, without giving a noticeably sour taste. Invert sugar syrup may also be produced without the use of acids or enzymes by thermal means alone: two parts granulated sucrose and one part water simmered for five to seven minutes will convert a modest portion to invert sugar.
All inverted sugar syrups are created from hydrolysing sucrose to glucose (dextrose) and fructose by heating a sucrose solution, then relying on time alone, with the catalytic properties of an acid or enzymes used to speed the reaction. Commercially prepared acid catalysed solutions are neutralised when the desired level of inversion is reached.
All constituent sugars (sucrose, glucose and fructose) support fermentation, so invert sugar solutions may be fermented as readily as sucrose solutions.
