Merlot

[Noclue]

I am looking to get my Dad a Birthday present. I know that he likes red wine mostly merlot. He just tried Port and is not liking it that much. He does not like Sheraz or chardoney. He tends to like the wines from Australia. I know that he never spends more then $10 for a bottle of wine so I was hoping to get something a little more pricey that he would not buy for himself.

Could anyone make a suggestion from what I have offered or is it to hard to tell what he would like?
