Not sure what this is. Have never planted pumpkin, melons or anything like it. It might just be a weed, but it doesn't seem like it is. Current size is approx. 700mm x 300mm. Close up leaf photo leaf size is about 150mm. Stems have little prickles/spikes
bump
Yes that definitely looks like some type of pumpkin/melon/squash or a relative. It could potentially be a wild or naturalized species.
