I have rock mellons coming up where i have buried kitchen scraps.. Should i pull them out or let them grow. I am in Ipswich Qld December 6 2018

You could let them grow - thin them out or separate them to 2-3' apart. I did this in Oct - the plants are just setting and growing fruit now. You may have to protect them later when they have fruit on from the sun. Better to plant them late August (away from frosts) or early Sept. The picking season is well under way in SE Qld now - probably finished by Xmas.

I live In Brisbane Australia I have a rock melon plant can I plant it now & How far do the vines go as I only have a small courtyard

Yes try growing it - I have some which are just starting to spread now. In really good soil and plenty of water they could spread a diameter of 4m. You could move/train the vine to a smaller area.

Where I live at Mount Bruce the temp can be cold with semi high wind is there any special care needed when tending to my rock melons

Just plant when they say so and try to protect them from the wind a bit. I didn't think they would grow in cold places.

You can grow rockies in the autumn. Probably don't taste as good as the spring ones. I had rockies in and harvested the last in Jan - the fruit left in the garden bed, their seeds were germinating with in a fortnight.

The older varieties use to start turning yellow and they would pull away from the vine easy when ripening. And you could smell the rocky smell. Called slipping. The new varieties in the super markets don't do this so it is a bit of a guessing game. They have green skin and the flesh is tough. I grew some of the newer ones and around ripening time we had 5
