There are many options. This is one that is easy to install, there will be similar ones in Aussie:
You can also search the forum (top right magnifying glass tool) for baggie if you want to feed simply. Others use mason jars (or jam jars) with tiny hole punched in the lid and then inverted over the inner cover/crown board.

I would also make up your syrup as 5:3 sugar to water. That saves the bees effort in dehydrating it for winter storage. I use 5lb of sugar to 3lb of water to make a little over 3 liters of syrup. I boil the water, turn off the heat, stir in the white sugar with a bit of star anise, and let it sit for about 20 mins to dissolve, stirring occasionally. When cool, I add about a teaspoon of Vitamin C powder (ascorbic acid) to prevent mold and promote healthy bees - nectar is acidic, and has Vit C in it too
