Ok, grab a chinese container or something similar in size.
Place a 1:1 ratio of vermiculite and water inside. So like 50grams of vermiculite to 50ml of water in the chinese container. Place the eggs inside the mixture (bout the centre of the container), half burry them if possible, making sure you dont rotate the eggs. Then place a piece of glad wrap between the container and lid, and place the lid on.
incubate between 28-30 degree- but if your in NSW you could probably get away with incubating at room temp.
