Is anything worthwhile under $10

[Englishman1]

Hi folks, complete wine newcomer here and also new to this forum. (Please forgive my naivette).

I'm interested to get your opinions on if there are any wines worthwhile that are under $10 a bottle.

I see all kinds of cheaper wines in my local store, mostly from Australia I believe, with names like Black Opal, Yellow Tail, Little Penguin etc...

I don't usually have more than $10 to spend on a bottle so if there are any reasonable brands I'd be very grateful for your advice! Thanks.
