How can I get selected item value in Angular 2 Material Autocomplete

You need to use [displayWith]="displayFn" inside <md-autocomplete> tag. Also, you have a pass the whole object as value.

<md-autocomplete #auto="mdAutocomplete" md-input-name="autocompleteField" required md-input-minlength="2" md-input-maxlength="18"  md-select-on-match required md-input-minlength="2" [displayWith]="displayFn">  <md-option *ngFor="let country of countries | async" [value]="country">    {{ country.Country }}  </md-option></md-autocomplete>

In your compoent, add:

displayFn(country): string {      return country ? country.Country : country;}

You can read more about it from Setting separate control and display values section in docs

Here is the final working version, hope it helps anyone else:
