You've got some great spots to check out, just a few extra awareness for you, Byron is a zoo for surfing over summer, absolutely loaded with people who have come for " the surfing experience" most will be there from countries with little or no surf culture and hence little or no awareness in the water can be mayhem and dangerous.
Lennox is a great point wave but has a difficult rock off, but here are beach peaks along all the beach.
Remember between each peak there is a rip and as you are on your travels take care.
Angourie point is a bit beyond upper beginner level when it is really working but there are still spots around there.
There are a couple of pocket guide books around showing the surf spots with a rating to match abilities.
One trouble often other travelers have the same guide.
Ballina and Yamba hope good chances.
Good luck and good surf
