Forget domestic vs international, and look at it this way.
Audited financials provide info to investors, owners, creditors etc. The extent that these people need financial info they can rely on determines if a company gets audited.
To raise capital (be public) assume that in all countries the exchanges and gov't regulatory bodies will require an audit, as well as other extra required info and disclosures.
For private company's it depends on the needs of the users. If you need credit lines you'll likely be audited. If you have a large diverse ownership base (ie family owned) you may also need it to satisfy those owners, etc.
