Copeland says bowling effectively in Sri Lanka has him confident he can take his game to the next level and he's hoping selectors will show faith.
"Ideally that's where more fruitful things come for me, doing the hard yards in Sri Lanka and I suppose the rewards can come when I'm on wickets which may suit my type of bowling a little bit more," said Copeland.
"I'd like to think so [I've done enough] but you never know and in different conditions the roles will change and things like that.
"There's still plenty of room for improvement but the fact I can be relatively successful in Sri Lanka, it gives me confidence I can be successful anywhere in the world.
"I think provided I don't get carried away and I keep working hard, then there's no reason why I can't."
Copeland is straight back into Sydney grade cricket with club side St George today, as he aims to maintain intensity ahead of the tour.
After claiming the prized scalp of Sri Lankan opener Tillakaratne Dilshan first-up in Galle, Copeland said he overcame his nerves and is now backing himself to knock over the Proteas' big guns.
"They're a formidable opposition but that's what you play cricket for. You play to test yourself against the best." His aim is to "get rid of Graeme Smith and AB de Villiers, and [Hashin] Amla and [Jacques] Kallis and all those blokes that everyone talks about".
