Don't worry about it. I've lived and worked for 30 years in the Arabian Gulf. All my jobs were paid in local currency.
In all the Gulf States there are banking and currency exchange and transfer services that are but a dream to folk living in (say) the UK. Instantanious currency exchange into virtually any hard currency in the world. You can purchase drafts on major banks in any most countries of the world. You can make speedy cash transfers to bank accounts in your home country or wherever you wish.
I don't know about the States or Australia and New Zealand but Oh that Britain could catch up to them in banking terms!
