You can take more than 100ml of liquid onto the flight, so long as it is purchased AFTER you go through the LAGs check point. I don't know about other Australian airports but Sydney has vending machines and plenty of shops air-side where you can buy bottled water, soft drinks, juice etc and can take them on the plane without any problem.
Unfortunately, coming home from Bali is another story and you have no place to purchase any drinks to take onto the plane as the LAGs check is at the departure gate.
