Can someone repair the euro please?

Exchange rates for the Euro are increasingly bad. Where I calculated my trip with an exchange rate of €0,61 to the Australian Dollar that has now shot up to €0,65. The US$ is also slowly on the rise. This way the trip will soon be 10% more expensive. That is actually a lot, considering the total cost. Still happy I prepaid so many hotels when the dollar was still at €0,67...
