Answer

Hi Hayley, it looks like you're writing an academic paper (or along the lines). In that case, out of habit I would probably say domestically first, and then internationally, because it seems more natural starting from small to big, if that makes sense. But yes, it is correct to say 'domestically' in this case.
You could also say 'on a domestic level', or 'on a national level'.

Answer

Saying 'nationally and internationally' is much clearer, because 'internationally' is like .. more than nationally.
'domestically and internationally' is also good.
