Yes. Any fish that has both fins and easily removed scales is considered kosher.
However, be careful that what you are being sold really is barramundi and not some cheaper fish that might not be kosher (though if you are ripped off chances are good that it's trevally, which is also kosher).
Yes. But make sure it really is barramundi. Back in the early '80s The Age found that more barramundi was sold in Victoria alone than was caught in Queensland. In other words, much of of what is sold as "barramundi" is something else. Often it's trevally, which is also kosher, though much cheaper; if you have been sold trevally instead of barramundi you've been ripped off, but at least your soul is safe. But you shouldn't rely on that. Make sure to buy fish with skin attached, so you can recognise the species.

The signs of a kosher fish are scales and fins. If the fish does not have either of these, then it is not a kosher fish. If it does, it is a kosher fish and one may eat it provided, of course, that it was prepared with kosher ingredients. According to "kashrut.com" (see link in related link section), the Grouper is indeed a kosher fish.
